Digital signatures are often employed in secure messaging
environments, where security and confidentiality are paramount. When a message is signed using a digital signature from a sender, the receiver knows that the identity of the received message can very likely be trusted. Pretty Good Privacy, or PGP
, has digital signatures built in to it, allowing users to digitally "sign", and therefore prove, that a message originated from them and no one else.
Digital signatures may employ encryption along with public and private keys
to send secure documents that may only be opened by the intended recipient.
