It is therefore useful to be able to ‘sign’ e-mails, as we use ink signatures on paper documents and letters, to give stronger proof of their origin. There are systems that allow such signatures to be created using certificates and certification agencies, however the most commonly used system, Pretty Good Privacy (PGP), uses a different approach and terminology.
