What is a digital signature?
A digital signature is a type of electronic signature that is uniquely linked to the signer, protects the document’s integrity, and ensures non-repudiation—meaning the signer cannot later deny having signed it.
Digital signatures are typically created using a certificate issued by a trust service provider, and often involve secure identification methods such as an eID or a passport.
Under the eIDAS Regulation, digital signatures are electronic signatures that meet the requirements for either an Advanced Electronic Signature (AdES) or a Qualified Electronic Signature (QES).

What is the difference between a simple electronic signature and a digital signature?
A Simple Electronic Signature (SES) is a basic way to sign electronically—like typing a name or clicking a button. It’s easy to use but offers minimal security and legal validity.
On the other hand, a digital signature (Advanced or Qualified under eIDAS) provides higher security and legal validity.
