why not just try all ciphers if cipher is not known ?

that's what my modified PGP 2.6.3ia-c version does.
(I added cast support to PGP 2.6.3ia)
If IDEA fails it just trys CAST5

== <EOF> ==
Disastry <-- GPG for Win32, PGP 2.6.3ia-c (supports CAST5)

Version: Netscape PGP half-Plugin 0.15 by Disastry / PGPsdk v1.7.1
