I don re-post mdayonliner (https://bitcointalk.org/index.php?action=profile;u=1432468) [Eng: Tutorial] PGP Signature - Encrypt/Decrypt message - Fingerprint (https://bitcointalk.org/index.php?topic=5469280.0)becos d pictures wey dey d main thread don spoil and d author no dey active again. As me and  Husna QA suggested (https://bitcointalk.org/index.php?topic=5469280.msg62952506#msg62952506), we don conclude say we go write one tutorial for Linux users.
