Hi Tom,

>>i didn't think of the possibility that it's an IDEA encrypted key....

If a key is older than 1999 and it is an RSA key the possibilty is not
that small, especially if it is created with PGP 5.x ;-)

This is strange.

I am not sure but using CAST5 as the sym algo for encryption does not
necessarly mean your passphrase is encrypted using CAST5, too. I have
not dig into the source of PGP 5 but there has been some discussions on
this point a few month ago (David?). PGP 5 can encrypt messages (and the
passphrase of course) using IDEA even if the key is of version 4
(DSA/ElGamal or RSA V4) like yours.

Have you ever tried to use the evaluation version of PGP to clear the
passphrases, export the keys and import them with GnuPG?

Or use the old PGP for linux version? (5.x)
