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. Parse successfully parses signed PKCS#7 DER bytes and extracts payload content and certificates
  2. Parse extracts signatures and validates signature authenticity using Verify and VerifyWithChain
  3. Parse successfully parses enveloped PKCS#7 DER bytes and decrypts ciphertext
  4. Parse returns an error when given invalid, empty, or truncated DER-encoded data
  5. GetOnlySigner returns the single signing certificate from parsed PKCS#7 signed data
