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. acme.ChallengeTypeTLSALPN01 evaluates to "tls-alpn-01" according to RFC 8737 §3.
  2. acme.Challenge with Type ChallengeTypeTLSALPN01 serializes to and deserializes from JSON preserving the challenge type and authorization metadata.
  3. acmez.TLSALPN01ChallengeCert generates a TLS certificate with the challenge identifier in DNSNames and an ECDSA P-256 private key.
  4. acmez.TLSALPN01ChallengeCert includes the critical acmeValidation-v1 extension containing the SHA-256 digest of keyAuthorization.
  5. TLS client and server configured with the generated challenge certificate and acmez.ACMETLS1Protocol complete a handshake negotiating "acme-tls/1".
  6. TLS client configured with an incompatible ALPN protocol fails to negotiate "acme-tls/1" against the challenge server.
