(Classic ASP) Create XAdES-T Signed XMLSee more XAdES ExamplesThis example signs XML using the XAdES-T profile. XAdES-T is a profile within the XAdES standard that adds support for secure timestamping of signatures. Secure timestamping involves adding a timestamp to the signature, indicating the exact time when the signature was applied. Timestamping enhances the long-term validity of signatures by providing evidence that the signature existed at a specific point in time, even if the signer's certificate has expired or been revoked. XAdES-T signatures include elements for embedding timestamp data within the XML signature, along with information about the timestamp authority and the timestamp verification process. XAdES-T signatures are suitable for scenarios where long-term validity and integrity of signatures are essential, such as in legal and regulatory contexts where archived documents may need to be validated years or decades later.
