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.NewDefault initializes a valid Config with default settings and a valid TLSConfig configured with GetCertificate.
  2. certmagic.New initializes a Config using a Cache and custom fields such as RenewalWindowRatio, DefaultServerName, and MustStaple.
  3. Config.CacheUnmanagedCertificatePEMBytes caches an unmanaged TLS certificate in memory and makes it retrievable via Config.GetCertificate for matching SNI.
  4. Config.GetCertificate falls back to the certificate for DefaultServerName when ClientHelloInfo.ServerName is empty.
