14 This is the DETAILS file for GnuPG which specifies some internals and
15 parts of the external API for GPG and GPGSM.
17 * Format of the colon listings
19 The format is a based on colon separated record, each recods starts
20 with a tag string and extends to the end of the line. Here is an

35 Note that new version of GnuPG or the use of certain options may add
36 new fields to the output. Parsers should not assume a limit on the
37 number of fields per line. Some fields are not yet used or only used
38 with certain record types; parsers should ignore fields they are not
39 aware of. New versions of GnuPG or the use of certain options may add
40 new types of records as well. Parsers should ignore any record whose
41 type they do not recognize for forward-compatibility.
43 The double =--with-fingerprint= prints the fingerprint for the subkeys
44 too. Old versions of gpg used a slightly different format and required
45 the use of the option =--fixed-list-mode= to conform to the format
49 ** Description of the fields
50 *** Field 1 - Type of record
53 - crt :: X.509 certificate
54 - crs :: X.509 certificate and private key available
55 - sub :: Subkey (secondary key)
57 - ssb :: Secret subkey (secondary key)
59 - uat :: User attribute (same as user id except for field 10).
61 - rev :: Revocation signature
62 - fpr :: Fingerprint (fingerprint is in field 10)
63 - pkd :: Public key data [*]
65 - rvk :: Revocation key
66 - tfs :: TOFU statistics [*]
67 - tru :: Trust database information [*]
68 - spk :: Signature subpacket [*]
69 - cfg :: Configuration data [*]
71 Records marked with an asterisk are described at [[*Special%20field%20formats][*Special fields]].
73 *** Field 2 - Validity
75 This is a letter describing the computed validity of a key.
76 Currently this is a single letter, but be prepared that additional
77 information may follow in some future versions. Note that GnuPG <
78 2.1 does not set this field for secret key listings.
80 - o :: Unknown (this key is new to the system)
81 - i :: The key is invalid (e.g. due to a missing self-signature)
82 - d :: The key has been disabled
83 (deprecated - use the 'D' in field 12 instead)
84 - r :: The key has been revoked
85 - e :: The key has expired
86 - - :: Unknown validity (i.e. no value assigned)
87 - q :: Undefined validity. '-' and 'q' may safely be treated as
88 the same value for most purposes
89 - n :: The key is not valid
90 - m :: The key is marginal valid.
91 - f :: The key is fully valid
92 - u :: The key is ultimately valid. This often means that the
93 secret key is available, but any key may be marked as
95 - w :: The key has a well known private part.
96 - s :: The key has special validity. This means that it might be
97 self-signed and expected to be used in the STEED system.
99 If the validity information is given for a UID or UAT record, it
100 describes the validity calculated based on this user ID. If given
101 for a key record it describes the validity taken from the best
104 For X.509 certificates a 'u' is used for a trusted root
105 certificate (i.e. for the trust anchor) and an 'f' for all other
108 *** Field 3 - Key length
110 The length of key in bits.
112 *** Field 4 - Public key algorithm
114 The values here are those from the OpenPGP specs or if they are
115 greather than 255 the algorithm ids as used by Libgcrypt.
119 This is the 64 bit keyid as specified by OpenPGP and the last 64
120 bit of the SHA-1 fingerprint of an X.509 certifciate.
122 *** Field 6 - Creation date
124 The creation date of the key is given in UTC. For UID and UAT
125 records, this is used for the self-signature date. Note that the
126 date is usually printed in seconds since epoch, however, we are
127 migrating to an ISO 8601 format (e.g. "19660205T091500"). This is
128 currently only relevant for X.509. A simple way to detect the new
129 format is to scan for the 'T'. Note that old versions of gpg
130 without using the =--fixed-list-mode= option used a "yyyy-mm-tt"
133 *** Field 7 - Expiration date
135 Key or UID/UAT expiration date or empty if it does not expire.
137 *** Field 8 - Certificate S/N, UID hash, trust signature info
139 Used for serial number in crt records. For UID and UAT records,
140 this is a hash of the user ID contents used to represent that
141 exact user ID. For trust signatures, this is the trust depth
142 separated by the trust value by a space.
144 *** Field 9 - Ownertrust
146 This is only used on primary keys. This is a single letter, but
147 be prepared that additional information may follow in future
148 versions. For trust signatures with a regular expression, this is
149 the regular expression value, quoted as in field 10.
151 *** Field 10 - User-ID
152 The value is quoted like a C string to avoid control characters
153 (the colon is quoted =\x3a=). For a "pub" record this field is
154 not used on --fixed-list-mode. A UAT record puts the attribute
155 subpacket count here, a space, and then the total attribute
156 subpacket size. In gpgsm the issuer name comes here. A FPR
157 record stores the fingerprint here. The fingerprint of a
158 revocation key is stored here.
159 *** Field 11 - Signature class
161 Signature class as per RFC-4880. This is a 2 digit hexnumber
162 followed by either the letter 'x' for an exportable signature or
163 the letter 'l' for a local-only signature. The class byte of an
164 revocation key is also given here, 'x' and 'l' is used the same
165 way. This field if not used for X.509.
167 *** Field 12 - Key capabilities
169 The defined capabilities are:
174 - a :: Authentication
175 - ? :: Unknown capability
177 A key may have any combination of them in any order. In addition
178 to these letters, the primary key has uppercase versions of the
179 letters to denote the _usable_ capabilities of the entire key, and
180 a potential letter 'D' to indicate a disabled key.
182 *** Field 13 - Issuer certificate fingerprint or other info
184 Used in FPR records for S/MIME keys to store the fingerprint of
185 the issuer certificate. This is useful to build the certificate
186 path based on certificates stored in the local key database it is
187 only filled if the issuer certificate is available. The root has
188 been reached if this is the same string as the fingerprint. The
189 advantage of using this value is that it is guaranteed to have
190 been been build by the same lookup algorithm as gpgsm uses.
192 For "uid" records this field lists the preferences in the same way
193 gpg's --edit-key menu does.
195 For "sig" records, this is the fingerprint of the key that issued
196 the signature. Note that this is only filled in if the signature
197 verified correctly. Note also that for various technical reasons,
198 this fingerprint is only available if --no-sig-cache is used.
200 *** Field 14 - Flag field
202 Flag field used in the --edit menu output
204 *** Field 15 - S/N of a token
206 Used in sec/ssb to print the serial number of a token (internal
207 protect mode 1002) or a '#' if that key is a simple stub (internal
208 protect mode 1001). If the option --with-secret is used and a
209 secret key is available for the public key, a '+' indicates this.
211 *** Field 16 - Hash algorithm
213 For sig records, this is the used hash algorithm. For example:
214 2 = SHA-1, 8 = SHA-256.
216 *** Field 17 - Curve name
218 For pub, sub, sec, and ssb records this field is used for the ECC
223 *** PKD - Public key data
225 If field 1 has the tag "pkd", a listing looks like this:
227 pkd:0:1024:B665B1435F4C2 .... FF26ABB:
229 ! !------ for information number of bits in the value
230 !--------- index (eg. DSA goes from 0 to 3: p,q,g,y)
233 *** TFS - TOFU statistics
235 This field may follows a UID record to convey information about
236 the TOFU database. The information is similar to a TOFU_STATS
239 - Field 2 :: tfs record version (must be 1)
240 - Field 3 :: validity - A number with validity code.
241 - Field 4 :: signcount - The number of signatures seen.
242 - Field 5 :: encrcount - The number of encryptions done.
243 - Field 6 :: policy - A string with the policy
244 - Field 7 :: signture-first-seen - a timestamp or 0 if not known.
245 - Field 8 :: signature-most-recent-seen - a timestamp or 0 if not known.
246 - Field 9 :: encryption-first-done - a timestamp or 0 if not known.
247 - Field 10 :: encryption-most-recent-done - a timestamp or 0 if not known.
249 *** TRU - Trust database information
250 Example for a "tru" trust base record:
252 tru:o:0:1166697654:1:3:1:5
255 - Field 2 :: Reason for staleness of trust. If this field is
256 empty, then the trustdb is not stale. This field may
257 have multiple flags in it:
259 - o :: Trustdb is old
260 - t :: Trustdb was built with a different trust model
261 than the one we are using now.
263 - Field 3 :: Trust model
265 - 0 :: Classic trust model, as used in PGP 2.x.
266 - 1 :: PGP trust model, as used in PGP 6 and later.
267 This is the same as the classic trust model,
268 except for the addition of trust signatures.
270 GnuPG before version 1.4 used the classic trust model
271 by default. GnuPG 1.4 and later uses the PGP trust
274 - Field 4 :: Date trustdb was created in seconds since Epoch.
275 - Field 5 :: Date trustdb will expire in seconds since Epoch.
276 - Field 6 :: Number of marginally trusted users to introduce a new
277 key signer (gpg's option --marginals-needed).
278 - Field 7 :: Number of completely trusted users to introduce a new
279 key signer. (gpg's option --completes-needed)
281 - Field 8 :: Maximum depth of a certification chain. (gpg's option
284 *** SPK - Signature subpacket records
286 - Field 2 :: Subpacket number as per RFC-4880 and later.
287 - Field 3 :: Flags in hex. Currently the only two bits assigned
288 are 1, to indicate that the subpacket came from the
289 hashed part of the signature, and 2, to indicate the
290 subpacket was marked critical.
291 - Field 4 :: Length of the subpacket. Note that this is the
292 length of the subpacket, and not the length of field
293 5 below. Due to the need for %-encoding, the length
294 of field 5 may be up to 3x this value.
295 - Field 5 :: The subpacket data. Printable ASCII is shown as
296 ASCII, but other values are rendered as %XX where XX
297 is the hex value for the byte.
299 *** CFG - Configuration data
301 --list-config outputs information about the GnuPG configuration
302 for the benefit of frontends or other programs that call GnuPG.
303 There are several list-config items, all colon delimited like the
304 rest of the --with-colons output. The first field is always "cfg"
305 to indicate configuration information. The second field is one of
308 - version :: The third field contains the version of GnuPG.
312 - pubkey :: The third field contains the public key algorithms
313 this version of GnuPG supports, separated by
314 semicolons. The algorithm numbers are as specified in
315 RFC-4880. Note that in contrast to the --status-fd
316 interface these are _not_ the Libgcrypt identifiers.
317 Using =pubkeyname= prints names instead of numbers.
319 : cfg:pubkey:1;2;3;16;17
321 - cipher :: The third field contains the symmetric ciphers this
322 version of GnuPG supports, separated by semicolons.
323 The cipher numbers are as specified in RFC-4880.
324 Using =ciphername= prints names instead of numbers.
326 : cfg:cipher:2;3;4;7;8;9;10
328 - digest :: The third field contains the digest (hash) algorithms
329 this version of GnuPG supports, separated by
330 semicolons. The digest numbers are as specified in
331 RFC-4880. Using =digestname= prints names instead of
334 : cfg:digest:1;2;3;8;9;10
336 - compress :: The third field contains the compression algorithms
337 this version of GnuPG supports, separated by
338 semicolons. The algorithm numbers are as specified
341 : cfg:compress:0;1;2;3
343 - group :: The third field contains the name of the group, and the
344 fourth field contains the values that the group expands
345 to, separated by semicolons.
347 For example, a group of:
348 : group mynames = paige 0x12345678 joe patti
350 : cfg:group:mynames:patti;joe;0x12345678;paige
352 - curve :: The third field contains the curve names this version
353 of GnuPG supports, separated by semicolons. Using
354 =curveoid= prints OIDs instead of numbers.
356 : cfg:curve:ed25519;nistp256;nistp384;nistp521
359 * Format of the --status-fd output
361 Every line is prefixed with "[GNUPG:] ", followed by a keyword with
362 the type of the status line and some arguments depending on the type
363 (maybe none); an application should always be willing to ignore
364 unknown keywords that may be emitted by future versions of GnuPG.
365 Also, new versions of GnuPG may add arguments to existing keywords.
366 Any additional arguments should be ignored for forward-compatibility.
368 ** General status codes
369 *** NEWSIG [<signers_uid>]
370 Is issued right before a signature verification starts. This is
371 useful to define a context for parsing ERROR status messages.
372 arguments are currently defined. If SIGNERS_UID is given and is
373 not "-" this is the percent escape value of the OpenPGP Signer's
374 User ID signature sub-packet.
376 *** GOODSIG <long_keyid_or_fpr> <username>
377 The signature with the keyid is good. For each signature only one
378 of the codes GOODSIG, BADSIG, EXPSIG, EXPKEYSIG, REVKEYSIG or
379 ERRSIG will be emitted. In the past they were used as a marker
380 for a new signature; new code should use the NEWSIG status
381 instead. The username is the primary one encoded in UTF-8 and %XX
382 escaped. The fingerprint may be used instead of the long keyid if
383 it is available. This is the case with CMS and might eventually
384 also be available for OpenPGP.
386 *** EXPSIG <long_keyid_or_fpr> <username>
387 The signature with the keyid is good, but the signature is
388 expired. The username is the primary one encoded in UTF-8 and %XX
389 escaped. The fingerprint may be used instead of the long keyid if
390 it is available. This is the case with CMS and might eventually
391 also be available for OpenPGP.
393 *** EXPKEYSIG <long_keyid_or_fpr> <username>
394 The signature with the keyid is good, but the signature was made
395 by an expired key. The username is the primary one encoded in
396 UTF-8 and %XX escaped. The fingerprint may be used instead of the
397 long keyid if it is available. This is the case with CMS and
398 might eventually also be available for OpenPGP.
400 *** REVKEYSIG <long_keyid_or_fpr> <username>
401 The signature with the keyid is good, but the signature was made
402 by a revoked key. The username is the primary one encoded in UTF-8
403 and %XX escaped. The fingerprint may be used instead of the long
404 keyid if it is available. This is the case with CMS and might
405 eventually also beñ available for OpenPGP.
407 *** BADSIG <long_keyid_or_fpr> <username>
408 The signature with the keyid has not been verified okay. The
409 username is the primary one encoded in UTF-8 and %XX escaped. The
410 fingerprint may be used instead of the long keyid if it is
411 available. This is the case with CMS and might eventually also be
412 available for OpenPGP.
414 *** ERRSIG <keyid> <pkalgo> <hashalgo> <sig_class> <time> <rc>
415 It was not possible to check the signature. This may be caused by
416 a missing public key or an unsupported algorithm. A RC of 4
417 indicates unknown algorithm, a 9 indicates a missing public
418 key. The other fields give more information about this signature.
419 sig_class is a 2 byte hex-value. The fingerprint may be used
420 instead of the keyid if it is available. This is the case with
421 gpgsm and might eventually also be available for OpenPGP.
423 Note, that TIME may either be the number of seconds since Epoch or
424 an ISO 8601 string. The latter can be detected by the presence of
431 - <fingerprint_in_hex>
432 - <sig_creation_date>
440 - [ <primary-key-fpr> ]
442 This status indicates that the signature is cryptographically
443 valid. This is similar to GOODSIG, EXPSIG, EXPKEYSIG, or REVKEYSIG
444 (depending on the date and the state of the signature and signing
445 key) but has the fingerprint as the argument. Multiple status
446 lines (VALIDSIG and the other appropriate *SIG status) are emitted
447 for a valid signature. All arguments here are on one long line.
448 sig-timestamp is the signature creation time in seconds after the
449 epoch. expire-timestamp is the signature expiration time in
450 seconds after the epoch (zero means "does not
451 expire"). sig-version, pubkey-algo, hash-algo, and sig-class (a
452 2-byte hex value) are all straight from the signature packet.
453 PRIMARY-KEY-FPR is the fingerprint of the primary key or identical
454 to the first argument. This is useful to get back to the primary
455 key without running gpg again for this purpose.
457 The primary-key-fpr parameter is used for OpenPGP and not
458 available for CMS signatures. The sig-version as well as the sig
459 class is not defined for CMS and currently set to 0 and 00.
461 Note, that *-TIMESTAMP may either be a number of seconds since
462 Epoch or an ISO 8601 string which can be detected by the presence
465 *** SIG_ID <radix64_string> <sig_creation_date> <sig-timestamp>
466 This is emitted only for signatures of class 0 or 1 which have
467 been verified okay. The string is a signature id and may be used
468 in applications to detect replay attacks of signed messages. Note
469 that only DLP algorithms give unique ids - others may yield
470 duplicated ones when they have been created in the same second.
472 Note, that SIG-TIMESTAMP may either be a number of seconds since
473 Epoch or an ISO 8601 string which can be detected by the presence
476 *** ENC_TO <long_keyid> <keytype> <keylength>
477 The message is encrypted to this LONG_KEYID. KEYTYPE is the
478 numerical value of the public key algorithm or 0 if it is not
479 known, KEYLENGTH is the length of the key or 0 if it is not known
480 (which is currently always the case). Gpg prints this line
481 always; Gpgsm only if it knows the certificate.
484 Mark the start of the actual decryption process. This is also
485 emitted when in --list-only mode.
487 Mark the end of the actual decryption process. This are also
488 emitted when in --list-only mode.
489 *** DECRYPTION_INFO <mdc_method> <sym_algo>
490 Print information about the symmetric encryption algorithm and the
491 MDC method. This will be emitted even if the decryption fails.
493 *** DECRYPTION_FAILED
494 The symmetric decryption failed - one reason could be a wrong
495 passphrase for a symmetrical encrypted message.
498 The decryption process succeeded. This means, that either the
499 correct secret key has been used or the correct passphrase for a
500 symmetric encrypted message was given. The program itself may
501 return an errorcode because it may not be possible to verify a
502 signature for some reasons.
504 *** SESSION_KEY <algo>:<hexdigits>
505 The session key used to decrypt the message. This message will
506 only be emitted if the option --show-session-key is used. The
507 format is suitable to be passed as value for the option
508 --override-session-key. It is not an indication that the
509 decryption will or has succeeded.
511 *** BEGIN_ENCRYPTION <mdc_method> <sym_algo>
512 Mark the start of the actual encryption process.
515 Mark the end of the actual encryption process.
517 *** FILE_START <what> <filename>
518 Start processing a file <filename>. <what> indicates the performed
525 Marks the end of a file processing which has been started
529 Mark the start of the actual signing process. This may be used as
530 an indication that all requested secret keys are ready for use.
532 *** ALREADY_SIGNED <long-keyid>
533 Warning: This is experimental and might be removed at any time.
535 *** SIG_CREATED <type> <pk_algo> <hash_algo> <class> <timestamp> <keyfpr>
536 A signature has been created using these parameters.
537 Values for type <type> are:
541 (only the first character should be checked)
543 <class> are 2 hex digits with the OpenPGP signature class.
545 Note, that TIMESTAMP may either be a number of seconds since Epoch
546 or an ISO 8601 string which can be detected by the presence of the
550 There are actually three related status codes to convey notation
553 - NOTATION_NAME <name>
554 - NOTATION_FLAGS <critical> <human_readable>
555 - NOTATION_DATA <string>
557 <name> and <string> are %XX escaped. The data may be split among
558 several NOTATION_DATA lines. NOTATION_FLAGS is emitted after
559 NOTATION_NAME and gives the critical and human readable flags;
560 the flag values are either 0 or 1.
562 *** POLICY_URL <string>
563 Note that URL in <string> is %XX escaped.
565 *** PLAINTEXT <format> <timestamp> <filename>
566 This indicates the format of the plaintext that is about to be
567 written. The format is a 1 byte hex code that shows the format of
568 the plaintext: 62 ('b') is binary data, 74 ('t') is text data with
569 no character set specified, and 75 ('u') is text data encoded in
570 the UTF-8 character set. The timestamp is in seconds since the
571 epoch. If a filename is available it gets printed as the third
572 argument, percent-escaped as usual.
574 *** PLAINTEXT_LENGTH <length>
575 This indicates the length of the plaintext that is about to be
576 written. Note that if the plaintext packet has partial length
577 encoding it is not possible to know the length ahead of time. In
578 that case, this status tag does not appear.
580 *** ATTRIBUTE <arguments>
581 The list or arguments are:
591 This is one long line issued for each attribute subpacket when an
592 attribute packet is seen during key listing. <fpr> is the
593 fingerprint of the key. <octets> is the length of the attribute
594 subpacket. <type> is the attribute type (e.g. 1 for an image).
595 <index> and <count> indicate that this is the N-th indexed
596 subpacket of count total subpackets in this attribute packet.
597 <timestamp> and <expiredate> are from the self-signature on the
598 attribute packet. If the attribute packet does not have a valid
599 self-signature, then the timestamp is 0. <flags> are a bitwise OR
601 - 0x01 :: this attribute packet is a primary uid
602 - 0x02 :: this attribute packet is revoked
603 - 0x04 :: this attribute packet is expired
605 *** SIG_SUBPACKET <type> <flags> <len> <data>
606 This indicates that a signature subpacket was seen. The format is
607 the same as the "spk" record above.
610 *** INV_RECP, INV_SGNR
611 The two similar status codes:
613 - INV_RECP <reason> <requested_recipient>
614 - INV_SGNR <reason> <requested_sender>
616 are issued for each unusable recipient/sender. The reasons codes
617 currently in use are:
619 - 0 :: No specific reason given
621 - 2 :: Ambigious specification
622 - 3 :: Wrong key usage
627 - 8 :: Policy mismatch
628 - 9 :: Not a secret key
629 - 10 :: Key not trusted
630 - 11 :: Missing certificate
631 - 12 :: Missing issuer certificate
633 - 14 :: Syntax error in specification
635 If no specific reason was given a previously emitted status code
636 KEY_CONSIDERED may be used to analyzed the problem.
638 Note that for historical reasons the INV_RECP status is also used
639 for gpgsm's SIGNER command where it relates to signer's of course.
640 Newer GnuPG versions are using INV_SGNR; applications should
641 ignore the INV_RECP during the sender's command processing once
642 they have seen an INV_SGNR. Different codes are used so that they
643 can be distinguish while doing an encrypt+sign operation.
645 *** NO_RECP <reserved>
646 Issued if no recipients are usable.
648 *** NO_SGNR <reserved>
649 Issued if no senders are usable.
651 *** KEY_CONSIDERED <fpr> <flags>
652 Issued to explian the lookup of a key. FPR is the hexified
653 fingerprint of the primary key. The bit values for FLAGS are:
655 - 1 :: The key has not been selected.
656 - 2 :: All subkeys of the key are expired or have been revoked.
658 *** KEYEXPIRED <expire-timestamp>
659 The key has expired. expire-timestamp is the expiration time in
660 seconds since Epoch. This status line is not very useful because
661 it will also be emitted for expired subkeys even if this subkey is
662 not used. To check whether a key used to sign a message has
663 expired, the EXPKEYSIG status line is to be used.
665 Note, that the TIMESTAMP may either be a number of seconds since
666 Epoch or an ISO 8601 string which can be detected by the presence
670 The used key has been revoked by its owner. No arguments yet.
672 *** NO_PUBKEY <long keyid>
673 The public key is not available
675 *** NO_SECKEY <long keyid>
676 The secret key is not available
678 *** KEY_CREATED <type> <fingerprint> [<handle>]
679 A key has been created. Values for <type> are:
680 - B :: primary and subkey
683 The fingerprint is one of the primary key for type B and P and the
684 one of the subkey for S. Handle is an arbitrary non-whitespace
685 string used to match key parameters from batch key creation run.
687 *** KEY_NOT_CREATED [<handle>]
688 The key from batch run has not been created due to errors.
691 These are several similar status codes:
693 - TRUST_UNDEFINED <error_token>
694 - TRUST_NEVER <error_token>
695 - TRUST_MARGINAL [0 [<validation_model>]]
696 - TRUST_FULLY [0 [<validation_model>]]
697 - TRUST_ULTIMATE [0 [<validation_model>]]
699 For good signatures one of these status lines are emitted to
700 indicate the validity of the key used to create the signature.
701 The error token values are currently only emitted by gpgsm.
703 VALIDATION_MODEL describes the algorithm used to check the
704 validity of the key. The defaults are the standard Web of Trust
705 model for gpg and the the standard X.509 model for gpgsm. The
708 - pgp :: The standard PGP WoT.
709 - shell :: The standard X.509 model.
710 - chain :: The chain model.
711 - steed :: The STEED model.
712 - tofu :: The TOFU model
714 Note that the term =TRUST_= in the status names is used for
715 historic reasons; we now speak of validity.
717 *** TOFU_USER <fingerprint_in_hex> <mbox>
719 This status identifies the key and the userid for all following
720 Tofu information. The fingerprint is the fingerprint of the
721 primary key and the mbox is in general the addr-spec part of the
722 userid encoded in UTF-8 and percent escaped. The fingerprint is
723 identical for all TOFU_USER lines up to a NEWSIG line.
725 *** TOFU_STATS <MANY_ARGS>
727 Statistics for the current user id.
729 The <MANY_ARGS> are the usual space delimited arguments. Here we
730 have too many of them to fit on one printed line and thus they are
731 given on 3 printed lines:
733 : <summary> <sign-count> <encryption-count>
734 : [<policy> [<tm1> <tm2> <tm3> <tm4>
735 : [<validity> [<sign-days> <encrypt-days>]]]]
737 Values for SUMMARY are:
738 - 0 :: attention, an interaction with the user is required (conflict)
739 - 1 :: key with no verification/encryption history
740 - 2 :: key with little history
741 - 3 :: key with enough history for basic trust
742 - 4 :: key with a lot of history
744 Values for POLICY are:
745 - none :: No Policy set
746 - auto :: Policy is "auto"
747 - good :: Policy is "good"
748 - bad :: Policy is "bad"
749 - ask :: Policy is "ask"
750 - unknown :: Policy is "unknown" (TOFU information does not
751 contribute to the key's validity)
753 TM1 is the time the first message was verified. TM2 is the time
754 the most recent message was verified. TM3 is the time the first
755 message was encrypted. TM4 is the most recent encryption. All may
756 either be seconds since Epoch or an ISO time string
759 VALIDITY is the same as SUMMARY with the exception that VALIDITY
760 doesn't reflect whether the key needs attention. That is it never
761 takes on value 0. Instead, if there is a conflict, VALIDITY still
762 reflects the key's validity (values: 1-4).
764 SIGN-COUNT and ENCRYPTION-COUNT are the number of messages that we
765 have seen that have been signed by this key / encryption to this
768 SIGN-DAYS and ENCRYPTION-DAYS are similar, but the number of days
769 (in UTC) on which we have seen messages signed by this key /
770 encrypted to this key.
772 *** TOFU_STATS_SHORT <long_string>
774 Information about the TOFU binding for the signature.
775 Example: "15 signatures verified. 10 messages encrypted"
777 *** TOFU_STATS_LONG <long_string>
779 Information about the TOFU binding for the signature in verbose
780 format. The LONG_STRING is percent escaped.
781 Example: 'Verified 9 messages signed by "Werner Koch
782 (dist sig)" in the past 3 minutes, 40 seconds. The most
783 recent message was verified 4 seconds ago.'
788 - PKA_TRUST_GOOD <addr-spec>
789 - PKA_TRUST_BAD <addr-spec>
791 Depending on the outcome of the PKA check one of the above status
792 codes is emitted in addition to a =TRUST_*= status.
795 *** GET_BOOL, GET_LINE, GET_HIDDEN, GOT_IT
797 These status line are used with --command-fd for interactive
798 control of the process.
800 *** USERID_HINT <long main keyid> <string>
801 Give a hint about the user ID for a certain keyID.
803 *** NEED_PASSPHRASE <long keyid> <long main keyid> <keytype> <keylength>
804 Issued whenever a passphrase is needed. KEYTYPE is the numerical
805 value of the public key algorithm or 0 if this is not applicable,
806 KEYLENGTH is the length of the key or 0 if it is not known (this
807 is currently always the case).
809 *** NEED_PASSPHRASE_SYM <cipher_algo> <s2k_mode> <s2k_hash>
810 Issued whenever a passphrase for symmetric encryption is needed.
812 *** NEED_PASSPHRASE_PIN <card_type> <chvno> [<serialno>]
813 Issued whenever a PIN is requested to unlock a card.
815 *** MISSING_PASSPHRASE
816 No passphrase was supplied. An application which encounters this
817 message may want to stop parsing immediately because the next
818 message will probably be a BAD_PASSPHRASE. However, if the
819 application is a wrapper around the key edit menu functionality it
820 might not make sense to stop parsing but simply ignoring the
821 following BAD_PASSPHRASE.
823 *** BAD_PASSPHRASE <long keyid>
824 The supplied passphrase was wrong or not given. In the latter
825 case you may have seen a MISSING_PASSPHRASE.
828 The supplied passphrase was good and the secret key material
832 *** IMPORT_CHECK <long keyid> <fingerprint> <user ID>
833 This status is emitted in interactive mode right before
834 the "import.okay" prompt.
836 *** IMPORTED <long keyid> <username>
837 The keyid and name of the signature just imported
839 *** IMPORT_OK <reason> [<fingerprint>]
840 The key with the primary key's FINGERPRINT has been imported.
843 - 0 :: Not actually changed
844 - 1 :: Entirely new key.
846 - 4 :: New signatures
848 - 16 :: Contains private key.
850 The flags may be ORed.
852 *** IMPORT_PROBLEM <reason> [<fingerprint>]
853 Issued for each import failure. Reason codes are:
855 - 0 :: No specific reason given.
856 - 1 :: Invalid Certificate.
857 - 2 :: Issuer Certificate missing.
858 - 3 :: Certificate Chain too long.
859 - 4 :: Error storing certificate.
861 *** IMPORT_RES <args>
862 Final statistics on import process (this is one long line). The
863 args are a list of unsigned numbers separated by white space:
868 - always 0 (formerly used for the number of RSA keys)
881 *** EXPORTED <fingerprint>
882 The key with <fingerprint> has been exported. The fingerprint is
883 the fingerprint of the primary key even if the primary key has
884 been replaced by a stub key during secret key export.
886 *** EXPORT_RES <args>
888 Final statistics on export process (this is one long line). The
889 args are a list of unsigned numbers separated by white space:
897 *** CARDCTRL <what> [<serialno>]
898 This is used to control smartcard operations. Defined values for
901 - 1 :: Request insertion of a card. Serialnumber may be given
902 to request a specific card. Used by gpg 1.4 w/o
904 - 2 :: Request removal of a card. Used by gpg 1.4 w/o scdaemon.
905 - 3 :: Card with serialnumber detected
906 - 4 :: No card available
907 - 5 :: No card reader available
908 - 6 :: No card support available
909 - 7 :: Card is in termination state
911 *** SC_OP_FAILURE [<code>]
912 An operation on a smartcard definitely failed. Currently there is
913 no indication of the actual error code, but application should be
914 prepared to later accept more arguments. Defined values for
917 - 0 :: unspecified error (identically to a missing CODE)
922 A smart card operaion succeeded. This status is only printed for
923 certain operation and is mostly useful to check whether a PIN
924 change really worked.
926 ** Miscellaneous status codes
928 No data has been found. Codes for WHAT are:
930 - 1 :: No armored data.
931 - 2 :: Expected a packet but did not found one.
932 - 3 :: Invalid packet found, this may indicate a non OpenPGP
934 - 4 :: Signature expected but not found
936 You may see more than one of these status lines.
938 *** UNEXPECTED <what>
939 Unexpected data has been encountered. Codes for WHAT are:
940 - 0 :: Not further specified
941 - 1 :: Corrupted message structure
943 *** TRUNCATED <maxno>
944 The output was truncated to MAXNO items. This status code is
945 issued for certain external requests.
947 *** ERROR <error location> <error code> [<more>]
948 This is a generic error status message, it might be followed by
949 error location specific data. <error code> and <error_location>
950 should not contain spaces. The error code is a either a string
951 commencing with a letter or such a string prefixed with a
952 numerical error code and an underscore; e.g.: "151011327_EOF".
953 *** WARNING <location> <error code> [<text>]
954 This is a generic warning status message, it might be followed by
955 error location specific data. <error code> and <location>
956 should not contain spaces. The error code is a either a string
957 commencing with a letter or such a string prefixed with a
958 numerical error code and an underscore; e.g.: "151011327_EOF".
959 *** SUCCESS [<location>]
960 Positive confirmation that an operation succeeded. It is used
961 similar to ISO-C's EXIT_SUCCESS. <location> is optional but if
962 given should not contain spaces. Used only with a few commands.
964 *** FAILURE <location> <error_code>
965 This is the counterpart to SUCCESS and used to indicate a program
966 failure. It is used similar to ISO-C's EXIT_FAILURE but allows
967 conveying more information, in particular a gpg-error error code.
968 That numerical error code may optionally have a suffix made of an
969 underscore and a string with an error symbol like "151011327_EOF".
970 A dash may be used instead of <location>.
973 The ASCII armor is corrupted. No arguments yet.
975 *** DELETE_PROBLEM <reason_code>
976 Deleting a key failed. Reason codes are:
978 - 2 :: Must delete secret key first
979 - 3 :: Ambigious specification
980 - 4 :: Key is stored on a smartcard.
982 *** PROGRESS <what> <char> <cur> <total> [<units>]
983 Used by the primegen and Public key functions to indicate
984 progress. <char> is the character displayed with no --status-fd
985 enabled, with the linefeed replaced by an 'X'. <cur> is the
986 current amount done and <total> is amount to be done; a <total> of
987 0 indicates that the total amount is not known. The condition
988 : TOTAL && CUR == TOTAL
989 may be used to detect the end of an operation.
991 Well known values for WHAT are:
993 - pk_dsa :: DSA key generation
994 - pk_elg :: Elgamal key generation
995 - primegen :: Prime generation
996 - need_entropy :: Waiting for new entropy in the RNG
997 - tick :: Generic tick without any special meaning - useful
998 for letting clients know that the server is still
1000 - starting_agent :: A gpg-agent was started because it is not
1001 running as a daemon.
1002 - learncard :: Send by the agent and gpgsm while learing
1003 the data of a smartcard.
1004 - card_busy :: A smartcard is still working
1006 <units> is sometines used to describe the units for <current> and
1007 <total>. For example "B", "KiB", or "MiB".
1009 *** BACKUP_KEY_CREATED <fingerprint> <fname>
1010 A backup of a key identified by <fingerprint> has been writte to
1011 the file <fname>; <fname> is percent-escaped.
1013 *** MOUNTPOINT <name>
1014 <name> is a percent-plus escaped filename describing the
1015 mountpoint for the current operation (e.g. used by "g13 --mount").
1016 This may either be the specified mountpoint or one randomly
1019 *** PINENTRY_LAUNCHED <pid>[:<extra>]
1020 This status line is emitted by gpg to notify a client that a
1021 Pinentry has been launched. <pid> is the PID of the Pinentry. It
1022 may be used to display a hint to the user but can't be used to
1023 synchronize with Pinentry. Note that there is also an Assuan
1024 inquiry line with the same name used internally or, if enabled,
1025 send to the client instead of this status line. Such an inquiry
1026 may be used to sync with Pinentry
1028 ** Obsolete status codes
1030 Removed on 2011-02-04. This is deprecated in favor of KEYEXPIRED.
1032 Obsolete. This status message used to be emitted for requests to
1033 use the IDEA or RSA algorithms. It has been dropped from GnuPG
1034 2.1 after the respective patents expired.
1035 *** SHM_INFO, SHM_GET, SHM_GET_BOOL, SHM_GET_HIDDEN
1036 These were used for the ancient shared memory based co-processing.
1037 *** BEGIN_STREAM, END_STREAM
1038 Used to issued by the experimental pipemode.
1041 * Format of the --attribute-fd output
1043 When --attribute-fd is set, during key listings (--list-keys,
1044 --list-secret-keys) GnuPG dumps each attribute packet to the file
1045 descriptor specified. --attribute-fd is intended for use with
1046 --status-fd as part of the required information is carried on the
1047 ATTRIBUTE status tag (see above).
1049 The contents of the attribute data is specified by RFC 4880. For
1050 convenience, here is the Photo ID format, as it is currently the
1051 only attribute defined:
1053 - Byte 0-1 :: The length of the image header. Due to a historical
1054 accident (i.e. oops!) back in the NAI PGP days, this
1055 is a little-endian number. Currently 16 (0x10 0x00).
1057 - Byte 2 :: The image header version. Currently 0x01.
1059 - Byte 3 :: Encoding format. 0x01 == JPEG.
1061 - Byte 4-15 :: Reserved, and currently unused.
1063 All other data after this header is raw image (JPEG) data.
1066 * Layout of the TrustDB
1068 The TrustDB is built from fixed length records, where the first byte
1069 describes the record type. All numeric values are stored in network
1070 byte order. The length of each record is 40 bytes. The first
1071 record of the DB is always of type 1 and this is the only record of
1074 The record types: directory(2), key(3), uid(4), pref(5), sigrec(6),
1075 and shadow directory(8) are not anymore used by version 2 of the
1080 Unused record or deleted, can be reused for any purpose. Such
1081 records should in general not exist because deleted records are of
1082 type 254 and kept in a linked list.
1084 ** Version info (RECTYPE_VER, 1)
1086 Version information for this TrustDB. This is always the first
1087 record of the DB and the only one of this type.
1089 - 1 u8 :: Record type (value: 1).
1090 - 3 byte :: Magic value ("gpg")
1091 - 1 u8 :: TrustDB version (value: 2).
1092 - 1 u8 :: =marginals=. How many marginal trusted keys are required.
1093 - 1 u8 :: =completes=. How many completely trusted keys are

1096 with =marginals= and =completes=, this value is used to
1097 check whether the cached validity value from a [FIXME
1098 dir] record can be used.

1112 - 1 u32 :: =trusthashtbl=. Record number of the trusthashtable.
1115 ** Hash table (RECTYPE_HTBL, 10)
1117 Due to the fact that we use fingerprints to lookup keys, we can
1118 implement quick access by some simple hash methods, and avoid the
1119 overhead of gdbm. A property of fingerprints is that they can be
1120 used directly as hash values. What we use is a dynamic multilevel
1121 architecture, which combines hash tables, record lists, and linked
1124 This record is a hash table of 256 entries with the property that
1125 all these records are stored consecutively to make one big
1126 table. The hash value is simple the 1st, 2nd, ... byte of the
1127 fingerprint (depending on the indirection level).
1129 - 1 u8 :: Record type (value: 10).
1131 - n u32 :: =recnum=. A table with the hash table items fitting into
1132 this record. =n= depends on the record length:
1133 $n=(reclen-2)/4$ which yields 9 for oure current record
1136 The total number of hash table records to form the table is:
1137 $m=(256+n-1)/n$. This is 29 for our record length of 40.
1139 To look up a key we use the first byte of the fingerprint to get
1140 the recnum from this hash table and then look up the addressed
1143 - If that record is another hash table, we use 2nd byte to index
1144 that hash table and so on;
1145 - if that record is a hash list, we walk all entries until we find
1147 - if that record is a key record, we compare the fingerprint to
1148 decide whether it is the requested key;
1151 ** Hash list (RECTYPE_HLST, 11)
1153 See hash table above on how it is used. It may also be used for
1156 - 1 u8 :: Record type (value: 11).
1158 - 1 u32 :: =next=. Record number of the next hash list record or 0
1160 - n u32 :: =rnum=. Array with record numbers to values. With
1161 $n=(reclen-5)/5$ and our record length of 40, n is 7.

1184 - 11 byte :: Not used.
1186 ** Free record (RECTYPE_FREE, 254)
1188 All these records form a linked list of unused records in the TrustDB.
1190 - 1 u8 :: Record type (value: 254)
1192 - 1 u32 :: =next=. Record number of the next rcord of this type.
1193 The record number to the head of this linked list is
1194 stored in the version info record.

1354 Description of some debug flags:
1356 - cardio :: Used by scdaemon to trace the APDUs exchange with the
1358 - clock :: Show execution times of certain functions.
1359 - crypto :: Trace crypto operations.
1360 - hashing :: Create files with the hashed data.
1361 - ipc :: Trace the Assuan commands.
1362 - mpi :: Show the values of the MPIs.
1363 - reader :: Used by scdaemon to trace card reader related code. For
1364 example: Open and close reader.
1368 * Miscellaneous notes
1371 For packet version 3 we calculate the keyids this way:
1372 - RSA :: Low 64 bits of n
1373 - ELGAMAL :: Build a v3 pubkey packet (with CTB 0x99) and
1374 calculate a RMD160 hash value from it. This is used
1375 as the fingerprint and the low 64 bits are the keyid.
1377 ** Simplified revocation certificates
1378 Revocation certificates consist only of the signature packet;
1379 "--import" knows how to handle this. The rationale behind it is to
1382 ** Documentation on HKP (the http keyserver protocol):
1384 A minimalistic HTTP server on port 11371 recognizes a GET for
1385 /pks/lookup. The standard http URL encoded query parameters are
1386 this (always key=value):
1388 - op=index (like pgp -kv), op=vindex (like pgp -kvv) and op=get (like
1391 - search=<stringlist>. This is a list of words that must occur in the key.
1392 The words are delimited with space, points, @ and so on. The delimiters
1393 are not searched for and the order of the words doesn't matter (but see
1396 - exact=on. This switch tells the hkp server to only report exact matching
1397 keys back. In this case the order and the "delimiters" are important.
1399 - fingerprint=on. Also reports the fingerprints when used with 'index' or
1402 The keyserver also recognizes http-POSTs to /pks/add. Use this to upload
1406 A better way to do this would be a request like:
1408 /pks/lookup/<gnupg_formatierte_user_id>?op=<operation>
1410 This can be implemented using Hurd's translator mechanism.
1411 However, I think the whole keyserver stuff has to be re-thought;
1412 I have some ideas and probably create a white paper.
1413 ** Algorithm names for the "keygen.algo" prompt
1415 When using a --command-fd controlled key generation or "addkey"
1416 there is way to know the number to enter on the "keygen.algo"
1417 prompt. The displayed numbers are for human reception and may
1418 change with releases. To provide a stable way to enter a desired
1419 algorithm choice the prompt also accepts predefined names for the
1420 algorithms, which will not change.

1438 If one of the "foo/*" names are used a "keygen.flags" prompt needs
1439 to be answered as well. Instead of toggling the predefined flags,
1440 it is also possible to set them direct: Use a "=" character
1441 directly followed by a comination of "a" (for authentication), "s"
1442 (for signing), or "c" (for certification).
