Digital Signature

A digital guarantee that a file has not been altered, as if it were carried in an “electronically-sealed” envelope. The "signature" is an encrypted digest (one-way hash function) of the text message, executable or other file.


A cryptographic process that allows the proof of the source (with non-repudiation) and the verification of the integrity of that data.
