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. softcas.New creates a CertificateAuthorityService instance when given a valid certificate chain and signer
  2. SoftCAS.Type returns apiv1.SoftCAS identifier
  3. SoftCAS.CreateCertificate signs and returns a valid leaf x509 certificate given a valid template and lifetime
  4. SoftCAS.CreateCertificate fails when template is nil
  5. SoftCAS.CreateCertificate fails when lifetime is zero
  6. Certificates issued by SoftCAS successfully verify against the root CA certificate chain
