PGP 6.5.3 is really, really old now, and predates a good amount of stuff that is now part of the OpenPGP standard, including some things that were added for security reasons. The real answer here is to get company 2 to upgrade to something newer. It doesn't have to be GPG - any recent PGP would be fine as well. Since that may not be under your control (I assume you are company 1 in the above), you can try adding the --pgp6 option to your GPG command line. This tells GPG to internally backdate itself, so it won't generate any messages using features or algorithms that were added to the standard after PGP 6. Even so, note that the --pgp6 option backdates to PGP 6.5.8, and company 2 is using a version even older than *that*.

PGP6 is able to use IDEA for encrypting and GPG doesn't decrypt it by default; try load-extension IDEA.DLL in GPG. You said ascii transfer but the pgp file is a binary one? -- Laurent Jumet KeyID: 0xCFAF704C ___ Gnupg-users mailing list Gnupg-users@gnupg.org http://lists.gnupg.org/mailman/listinfo/gnupg-users

The problem was on the PGP end. The company using PGP6.x couldn't decrypt, and the error message, bad session keys indicates that the it didn't recognize the algorithm used, (probably AES or another one that came after PGP 6.x. ) David's advice of using the option of --PGP6 on the GnuPG side will make everything work again on the PGP end. vedaal ___ Gnupg-users mailing list Gnupg-users@gnupg.org http://lists.gnupg.org/mailman/listinfo/gnupg-users
