Hi again, this problem interests me as a newbie, because I will probably encounter it myself. Here is a clue from the README: If you already have a DSA key from PGP 5 (they call them DH/ElGamal) you can simply copy the pgp keyrings over the GnuPG keyrings after running gpg once to create the correct directory. Maybe that is where the confusion is. PgP5 calls their DSA key DH/ElGamal? Is this not what the snippet above says? Maybe when you do your new --gen-key, you could use option 2, generate DSA key only. That way you will encrypt with DSA, which should be compatible with pgp5. What do you think, have you tried it yet? zentara
