Of course not: pgp 2.x versions only use IDEA for conventional encryption.

That's worse. I tested this with pgp 2.6.3i and gpg 1.0.2: a file that is conventional encrypted by pgp 2.6.3i can be decrypted with gpg if you put the following in the options file: compress-algo 2 cipher-algo IDEA digest-algo MD5 s2k-cipher-algo IDEA s2k-digest-algo MD5 rfc1991 allow-non-selfsigned-uid I did not find a method for the other way arround: a file that is conventionally encrypted with gpg 1.0.2 with this options always gives a bad passphrase error in pgp 2.6.3i. What I also notice is that with these options gpg seems not to compress the output file. Is compress-algo 2 obly usable for decryption? -- ir. J.C.A.
