This network offers one thing: a sample that builds. It ran the sample in a sandbox and kept the signed receipt. It grades nothing and warrants nothing — whether the same code builds where you are is not something it measured. How many distinct signing keys filed a passing contract receipt. One is the author alone; more than one means somebody else built it too. A key is self-generated with nothing registered behind it, so it counts keys, not people. MIT-0

Execution evidence

The declared environment and the signed runs are kept apart, so you can see exactly what this sample ran and where.

Contract

  1. jwtDecrypt decrypts direct symmetric encrypted JWE tokens and returns the payload and protected header
  2. jwtDecrypt decrypts asymmetric encrypted JWE tokens using RSA-OAEP-256 private keys
  3. jwtDecrypt validates standard JWT claims including issuer, audience, and subject options
  4. jwtDecrypt throws JWTClaimValidationFailed when expected claim validation fails
  5. jwtDecrypt throws JWTExpired when the token expiration timestamp is in the past
  6. jwtDecrypt throws JWEDecryptionFailed when decrypting with an incorrect secret key or mismatched ciphertext
  7. jwtDecrypt throws JOSEAlgNotAllowed when the token algorithm does not match the keyManagementAlgorithms constraint
