Here are the PuTTY files themselves:

LEGAL WARNING: Use of PuTTY, PSCP, PSFTP and Plink is illegal in countries where encryption is outlawed. I believe it is legal to use PuTTY, PSCP, PSFTP and Plink in England and Wales and in many other countries, but I am not a lawyer and so if in doubt you should seek legal advice before downloading it. You may find this site useful (it's a survey of cryptography laws in many countries) but I can't vouch for its correctness.

Use of the Telnet-only binary (PuTTYtel) is unrestricted by any cryptography laws.

There are cryptographic signatures available for all the files we offer below. We also supply cryptographically signed lists of checksums. To download our public keys and find out more about our signature policy, visit the Keys page. If you need a Windows program to compute MD5 checksums, you could try the one at this site. (This MD5 program is also cryptographically signed by its author.)

Binaries

The latest release version (beta 0.63). This will generally be a version I think is reasonably likely to work well. If you have a problem with the release version, it might be worth trying out the latest development snapshot (below) to see if I've already fixed the bug, before reporting it to me.

Pre-releases of 0.64. These are snapshots of the PuTTY code which we hope will shortly become the 0.64 release. They do not contain all the features of the development snapshots (below), but they contain bug fixes that are not present in the 0.61 release, and should be stable. If you find any serious bugs in these, let us know, so we can fix them before making a proper release!

(The filename of the pre-release installer contains the revision number of the pre-release code, so it may change sometimes.)

The latest development snapshot. This will be built every day, automatically, from the current development code - in whatever state it's currently in. If you need a fix for a particularly crippling bug, you may well be able to find a fixed PuTTY here well before the fix makes it into the release version above. On the other hand, these snapshots might sometimes be unstable.

(The filename of the development snapshot installer contains the snapshot date, so it will change every night.)

Source code

This is the source code for all of the PuTTY utilities.

For convenience, we provide several versions of the source code, for different platforms. The actual content does not differ substantially between Windows and Unix archives; the differences are mostly in formatting (filenames, line endings, etc).

If you want to do any PuTTY development work, we strongly recommend starting with development snapshot code. We frequently make large changes to the code after major releases, so code based on the current release will be hard for us to use.

Unix source code

These .tar.gz source archives should build the latest release version, and latest development snapshot, of PuTTY for Unix.

To build the release or pre-release source, you will need to unpack one of these archives, change into the "unix" subdirectory, and type "make -f Makefile.gtk". To build the development snapshot source, you can just do the standard thing of ./configure && make. See the file "README" for more information.

(The filename of the development snapshot source archive contains the snapshot date, so it will change every night. The pre-release source archive similarly contains a revision number.)

Windows source code

See the file "README" for more information on building PuTTY from source.

Access via git

If you want to keep track of the PuTTY development right up to the minute, or view the change logs for each of the files in the source base, you can access the PuTTY master git repository directly, using a command such as

git clone git://git.tartarus.org/simon/putty.git

Alternatively, you can browse the repository on the web, here.
