These are the options I picked up out of the archives somewhere and they've been working like a charm: --compress-algo 2 --cipher-algo IDEA --digest-algo MD5 --s2k-cipher-algo IDEA --s2k-digest-algo MD5 --rfc1991 --allow-non-selfsigned-uid I routinely have to decrypt traffic from First-Teams, sometimes once a week or so, sometimes several times a day, that is pgp-2.6.x encrypted, conventional encryption. This was the incantation that made it all work with gpg-1.0.3.
