A digital signature is an electronic signature that can be used to authenticate the identity of the sender of a message or the signer of a document, and also to ensure that the original content of the message or document that has been sent is unchanged. Digital signatures are easily transportable, cannot be imitated by someone else, and can be automatically time-stamped. Digital signatures employ a type of symmetric cryptograhy and another asymmetric as the so called “hash”.
