I've recently (in the last few days) been trying to make Mailcrypt
3.5.4, and PGP 6.5.1 (command line) talk to each other (with FSF Emacs
20.3.1 and pGnus 0.92, all on a Windows 98 system). Here's what I've
learned:

 - 6.5.1 is close enough to 2.6.2 that mods should be based on
       mc-pgp.el rather than mc-pgp5.el.

 - Signing and encrypting can be made to work either by using the
       +COMPATIBLE flag throughout mc-pgp.el or changing key-regexp in
       mc-pgp-lookup-key to:
       "^\\(\\(DSS\\|RSA\\)\\s +\\S +\\s +0x\\(\\S *\\)\\s +\\S +\\s +\\(.*\\)\\)$"

 - The bug that prevents -f and +BATCHMODE from working together
       triggers a bug in mc-pgp-decrypt-region such that if one
       naievely removes +BATCHMODE, you get wedged asking for a
       password. This can be worked around with the following patch
       (which is more like what mc-pgp5.el and mc-gpg.el do; I presume
       that it isn't fixed here because it doesn't cause problems with
       PGP 2.6.2):
