What is a digital signature?
A digital signature is an electronic form of a signature that can be used to authenticate the identity of the sender of a message or the signer of a document, and ensure that the original content of the message or document that has been sent is unchanged. Digital signatures are easily transportable and cannot be imitated by someone else. The ability to ensure that the original signed message arrived means that the sender cannot easily disclaim it later.
