Is there a way to perform a digital signature with a JSON format? Like XadES, but simpler

462 Views Asked by At

I'm signing documents and adding a timestamp seal using the XadES-T format. I think that a JSON format would simplify the signature and validation process, is there a way to sign documents and add a timestamp seal in JSON?

JWT signatures itself does not include timestamps in its spec. But you could wrap the JSON in a PKCS#7 Content Signed Message with a timestamp.
