I live in Europe and there ' s no such thing as curse words here . I think it ' s because we ' re so superior to Amerikkkans . <| sep |> or , don ' t let your team die in the first place no need to even go with resurrection . <| sep |> PGP works on the basis of something called asymmetric cryptography , also known as public key cryptography . In ordinary symmetric cryptography if two people want to communicate they need to share a key between themselves but keep it a secret only between themselves , this is inconvenient . With public key encryption there are two keys , an encryption key that is made public and a decryption key which is kept private by the owner . Now anyone can send a message to the owner of the private key that is encrypted in such a way that only the private key owner can decrypt . Digital signatures , which are what is being used in the post above are the reverse of this . The block of gibberish is the signature for the message it is generated from the contents of the message and the poster ' s private key . It is generated in such a way that anyone with the poster ' s public key which truzoom has presumably published somewhere can verify that only someone with the corresponding private key could have generated it . If you were to alter the message you ' d need truzoom ' s private key to generate a valid signature .
