(DataFlex) XAdES using TSA Requiring Client Certificate

See more XML Digital Signatures Examples

Demonstrates how to create an XMLDSig (XAdES) signed document which includes an EncapsulatedTimestamp using a TSA (TimeStamp Authority) server requiring client certificate authentication. One such TSA is https://www3.postsignum.cz/TSS/TSS_crt/
