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. keyutil.GenerateKeyPair("EC", "P-256", 0) returns non-nil ECDSA public and private keys matching elliptic curve P-256
  2. keyutil.GenerateKeyPair("RSA", "", 2048) returns non-nil RSA key pair with at least 2048 bit modulus
  3. keyutil.GenerateKeyPair("OKP", "Ed25519", 0) returns non-nil Ed25519 public and private keys
  4. keyutil.VerifyPair returns nil when verifying matching generated key pairs for EC, RSA, and OKP
  5. keyutil.Fingerprint returns a non-empty string fingerprint for generated public keys
  6. keyutil.GenerateKeyPair returns an error when given an unsupported key algorithm
  7. keyutil.VerifyPair returns an error when verifying mismatched public and private keys
