  1. JOSE Working Group Specifications Status: JWS, JWE, JWK, JWA Mike Jones August 1, 2012

  2. JSON Web Signature (JWS) • Specification very stable • No normative changes, other than minor additions and clarifications, since March 2011 (when JWS was separated from the JWT spec) • Well over a dozen (known) implementations • Some in production use • Significant interop testing has already occurred • Open issues only about potential extensions

  3. JSON Web Encryption (JWE) • Specification stabilizing • Multiple interoperable implementations using RSAES-PKCS1-V1_5, RSA OAEP, AES CBC, AES GCM • Functionality rounded out based on feedback from implementers • Supports symmetric and asymmetric encryption, key agreement, use of random CMK, and direct use of shared and agreed upon keys • Remaining open issues identified • WG feedback needed to close and prepare for WGLC

  4. JSON Web Key (JWK) • Specification very stable • Only normative changes since April 2011 when created were to rename some fields • About a dozen (known) implementations • Significant interop testing has already occurred • Only one remaining open issue • (on whether to make minor functionality addition)

  5. JSON Web Algorithms (JWA) • Core algorithms stable • Supports interoperable JWS, JWE, JWK implementations • Open issues mostly about fine tuning details of using non-AEAD algorithms • Refining inputs to Concat KDF • Possibly defining matched enc/int/kdf combinations • Remaining open issues identified • WG feedback needed to close and prepare for WGLC
