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. noise.NewCipherSuite constructs a CipherSuite with specified DH, Cipher, and Hash algorithms
  2. noise.NewHandshakeState initializes a HandshakeState using Config
  3. noise.HandshakeState.WriteMessage and ReadMessage complete a Noise handshake and return CipherStates
  4. noise.CipherState.Encrypt encrypts plaintext with authentication and Decrypt recovers original plaintext
  5. noise.DH25519 generates valid keypairs for authenticated HandshakeXX
