CHANGES

1.5 (2024-12-18)

  • SDJWT class
    • Added getHashAlgorithm() method.
    • Added getSDHash() method.

1.4 (2023-11-23)

  • SDConstants class
    • Replaced "type" in the RETAINED_CLAIMS set with "vct" to align with the breaking change by the draft 01 of the SD-JWT VC specification.

1.3 (2023-06-22)

  • New types
    • SDObjectDecoder class
    • SDObjectEncoder class

1.2 (2023-06-19)

Update to follow the following normative changes of the SD-JWT specification.

  1. A tilde (~) is appended to "Combined Format for Issuance", resulting in that there is no formal difference between (a) Combined Format for Issuance and (b) Combined Format for Presentation without a binding JWT.
  2. The format of the base JSON of Disclosure for an array element has changed from [salt, [name, index], value] to [salt, value].
  3. Disclosures for array elements are not put in the _sd array. Instead, each array element is replaced with {"...": "<digest>"}.
  4. Terminology changes. The terms "Combined Format for Issuance" and "Combined Format for Presentation" are obsoleted, and the entire combined format is called "SD-JWT".
