Subject: sigkey handling: Introduce sigkeyid type
X-Git-Tag: v0.6.0~216
X-Git-Url: http://www.chiark.greenend.org.uk/ucgi/~ian/git?p=secnet.git;a=commitdiff_plain;h=dafb749b7f5f0cd26093062da4ec547458f2d029

sigkey handling: Introduce sigkeyid type

We provide helper macros for use with printf.

The reference to pubkeys.fl.pl comment is to code which doesn't exist
yet but comes later.
