Definition of Signature

A Signature is a cryptographic mark appended to a message, which is formed by encrypting the message with the signing user's Private Key. The user's Public Key is usually attached as well, for convenience.

A Signature effectively demonstrates that the purported sender of the message did, in fact, sign it, since only he possesses the key required to encrypt it in such a way that his Public Key will successfully decrypt it.
