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. compactDecrypt decrypts direct symmetric JWE tokens (dir + A256GCM), returning plaintext and protected header
  2. compactDecrypt decrypts key-wrapped JWE tokens (A256KW + A256GCM) using symmetric wrapping key
  3. compactDecrypt decrypts asymmetric JWE tokens (RSA-OAEP-256) using private key
  4. compactDecrypt supports dynamic key resolution via key resolver callback function
  5. compactDecrypt rejects disallowed key management or content encryption algorithms with JOSEAlgNotAllowed
  6. compactDecrypt rejects malformed compact JWE strings with JWEInvalid
  7. compactDecrypt rejects decryption with incorrect key or tampered ciphertext with JWEDecryptionFailed
