Overview

const encodedSdjwt = await sdjwt.issue(claims, privateKey, disclosureFrame, options);

Parameters

• claims: the payload of SD JWT [Object]
• privateKey: private key to sign SD JWT [Uint8Array | KeyLike]
• disclosureFrame: to define which properties should be selectively diclosable (optional, if not provided, there is no disclosure)
• options: (optional)

options?: {
  sign_alg?: string; // sign algorithm
  hash_alg?: string; // hash algorithm
  kb?: {
    alg: string; // sign algorithm to key binding JWT 
    payload: kbPayload; // key binding payload
    privateKey: Uint8Array | KeyLike; // private key to sign key binding  JWT
  };
