i've finally managed to finish the first of a total of 4 translations.
the tutorial created by Learn Bitcoin: [Eng: Tutorial] PGP Signature - Encrypt/Decrypt message (Linux Only) can now be accessed here for all german-speaking users: [Linux Anleitung] PGP Signature - Nachricht verschlüsseln/entschlüsseln

i hope i can now gradually deliver the remaining three translations... unfortunately i'm very pressed for time at the moment
