Advanced Electronic Signatures (AES)

An electronic signature refers to data linked to electronic information that allows for the identification of the signer or signature creator and the verification of the integrity of the signed electronic information. Typically, the electronic information consists of electronic documents such as PDFs. There are three forms of electronic signatures: the (simple) electronic signature, the advanced electronic signature (Advanced Electronic Signature, AES), and the qualified electronic signature (QES). They all share the commonality that they are encrypted using asymmetric cryptography.
