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. NewSignedData and AddSigner create verifiable PKCS#7 detached and attached digital signatures
  2. Parse reads signed PKCS#7 structures and verifies payload integrity against signer certificates
  3. Verify and VerifyWithChain validate PKCS#7 signatures against trusted x509 certificate pools
  4. Encrypt and Decrypt envelope data for recipient x509 certificates and recover original plaintext
  5. GetOnlySigner returns the leaf signer certificate from a single-signer PKCS#7 payload
