FAQ - Signatur

What is the difference between a signature and a certificate?

An electronic signature is attached to a document. When used with cryptographic techniques, each individual signature contains information about the signed document and the signatory’s private key (i.e. the signature creation data). Consequently, every signature has a different appearance. You do not need a certificate to generate a signature.

The certificate is the online ID document. By referring to the signature validation data (i.e. the signatory’s public key) in the certificate, the recipient of a message can verify whether the signature was created using the corresponding private key. The recipient can then also derive the signatory’s name from the certificate.
