− | + | {{w|Pretty Good Privacy|PGP}} (or {{w|GNU_Privacy_Guard|GPG}} under linux) is a program which can be used to encrype and sign messages sent as emails. Encrypting the message would prevent anybody from reading it if they didn't have the key to decrypt. Signing the message would mean that the message can be verified as un-altereted, if the reader was to check the message against the signature. People who uses such program typically only uses the feature to sign the message, since entryping it (which would give you the privacy) would mean that almost nobody would be able to read it, including the intended receipient as they rarely would have the keys and software installed to decrypt the message. hence the irony here is that nobody actually verifies the "signature" either, but feel secure that the m essage appears to be signed. | |
