Signature of Documents

Like a signature autograph which aims to identify the person or entity responsible for issuing a paper document, the digital signature has the intention of sign electronic documents and identify their origin.

A digital signature is an electronic signature based on the system of asymmetric-key cryptography consisted of an algorithm or series of algorithms, which is generated by a pair of asymmetric keys, one private and one public. This procedure allows the holder to use the private key to establish the authorship of the electronic document. The receiver of the message uses the public key to verify that the signature was created from the use of the corresponding private key and to verify if the electronic document was changed after the introduction of digital signature.
