This library implements the Selective Disclosure JWT (SD-JWT) specification: draft-ietf-oauth-selective-disclosure-jwt-06.

• Create and sign SD-JWT tokens
  • Choose selectively disclosable payload fields (SD fields)
  • Create digests for SD fields and insert into JWT body payload
  • Create and append encoded disclosure strings for SD fields to JWT token
  • Add random or fixed number of decoy digests on each nested object property
• Present SD-JWT tokens
  • Selection of fields to be disclosed
  • Support for appending optional holder binding
• Full support for nested SD fields and recursive disclosures
• Parse SD-JWT tokens and restore original payload with disclosed fields
• Verify SD-JWT token
  • Signature verification
  • Hash comparison and tamper check of the appended disclosures
• Support for integration with various crypto libraries and frameworks, to perform the cryptographic operations and key management
