WebApr 11, 2024 · An Issuer MAY add additional digests to the SD-JWT that are not associated with any claim. The purpose of such "decoy" digests is to make it more difficult for an attacker to see the original number of claims contained in the SD-JWT. It is RECOMMENDED to create the decoy digests by hashing over a cryptographically secure random number.
