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. certmagic.ED25519 is the KeyType constant for the ed25519 public-key signature algorithm.
  2. certmagic.StandardKeyGenerator with KeyType certmagic.ED25519 generates an ed25519.PrivateKey of 64 bytes.
  3. certmagic.StandardKeyGenerator with KeyType certmagic.ED25519 produces a public key of type ed25519.PublicKey of 32 bytes capable of verifying signatures.
  4. certmagic.StandardKeyGenerator returns an error when configured with an unsupported KeyType.
