And the bottom line is? I don't think I understand how this will help me. I would really appreciate any help to get this fixed. I want to encypt my mail to my pgp5-using friend. My key is generated by gpg so the PGP5-GnuPG HOWTO is of little or no use. I started to get GnuPG to work with PGP about 2 month ago but still haven't got it work. Since I'm completely without knowledge on how GPG, PGP and related issues works in practice (what to putin which configfile etc.) I cannot do this by myself. I think this is my 4:th or 5:th cry for handguided help. Time to give up? Am I the only one to communicate with PGP5 users? /Jonas, who just checked the documentation again but found no help. -- ( Jonas Steverud @ !
