Timestamp Authority

Learn how SIGNiX timestamps ensure the integrity and authenticity of digital signatures by securely recording the time of signing with a trusted Timestamp Authority.

A timestamp is a digitally signed record that associates a reliable time with some other record. Timestamps can be used to prove that the document existed in a specific form at the indicated time.

SIGNiX uses timestamps to record the time that any digital signature was created and uses the SIGNiX Timestamp Authority to create all timestamps.

A Timestamp Authority (TA) is a service that records the time of an event based on time sources that are not from the signer’s computer, and thus can’t be manipulated with.

SIGNiX is certified as a Timestamp Authority. SIGNiX timestamps are digitally signed using DSS with a 2048-bit key and are in PKIX Time-Stamp Protocol (RFC 3161) format. SIGNiX can also use certificates from other Certificate Authorities and can leverage their time-stamping services as well.
