The thing here is that the short keyid is not from the specification but
a convenience thing PGP-2 implemented (which actually did not compute
the keyid from the fingerprint). 

Yes, it would indeed be nicer if we could work with the keyid in the
same way as git handles a commit id.  Unfortunately it will be pretty
hard to change how the short keyid is derived from the long keyid or
even use arbitrary sized keyids of fingerprints.  In GnuPG the keyid is
a "u32 kid[2]" and this is used a lot all over the code, for example:

  fprint ("long  keyid: %08lX%08lX\n", (ulong)kid[0], (ulong)kid[1]);
  fprint ("short keyid: %08lX\n",      (ulong)kid[1]);

See doc/HACKING for hints.  Please also be aware that for any unattended
use you need to use the --with-colons and --status-fd interfaces.  Some
ignore this advice and thus we are nice and try to minimize all changes
even to the human readable output format.


Salam-Shalom,
