GnuPG and PGP 5.0 compatibility problem

[Stefan Oltmanns]

Hello,

I got a problem with GnuPG and PGP 5.0:
Also PGP 5 accepts my key, it is not possible for PGP 5 to encrypt with 
my key. It´s not even displayed in the selection dialog when I try to 
encrypt something (it shows identities correct in key list (but 
expiration not)).

I read in the FAQ that PGP 5.0 does not accept ElGamal keys of type 20, 
but my key doesn´t seem to be of that type (--list-packets says "version 
4, algo 16, created 1153340019, expires 0")

There seem to be another problem, do you have any idea how to solve it?

In case you´re wondering, I do have PGP only for testing purpose, 
because I can´t get EUMEL of the 1822direkt bank (a system that sends 
you a OpenPGP encrypted mail with financial transactions on your 
account) to work, they use PGP 5.0.

Sincerely,
Stefan
