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. generateSecret generates HMAC secret CryptoKey for HMAC algorithms (HS256, HS384, HS512) compatible with SignJWT and jwtVerify
  2. generateSecret generates AES-GCM secret CryptoKey for AES-GCM algorithms (A128GCM, A192GCM, A256GCM) compatible with direct JWE encryption
  3. generateSecret generates AES-KW secret CryptoKey for AES key wrapping algorithms (A128KW, A192KW, A256KW)
  4. generateSecret generates raw Uint8Array symmetric keys of appropriate byte length for AES-CBC-HMAC-SHA2 algorithms (A128CBC-HS256, A192CBC-HS384, A256CBC-HS512)
  5. generateSecret respects the extractable option, allowing JWK export when extractable is true and preventing it when false
  6. generateSecret rejects unsupported or asymmetric algorithm identifiers with JOSENotSupported (ERR_JOSE_NOT_SUPPORTED)
