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. exportJWK exports extractable RSA private and public keys to JWK format with kty RSA and appropriate components
  2. exportJWK exports extractable EC private and public keys with kty EC, crv P-256, coordinates x, y, and private parameter d
  3. exportJWK exports extractable OKP (Ed25519) private and public keys with kty OKP, crv Ed25519, public coordinate x, and private scalar d
  4. exportJWK exports symmetric CryptoKey and Uint8Array secrets to JWK format with kty oct and base64url-encoded k parameter
  5. exportJWK results can be imported back with importJWK to successfully sign and verify JWS payloads
  6. exportJWK rejects with TypeError when given non-extractable CryptoKey
  7. exportJWK rejects with TypeError when invoked with invalid key inputs such as null, undefined, numbers, or non-key objects
