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 parses DER-encoded PKCS#7 SignedData payload into a PKCS7 instance and preserves content bytes
  2. Verify verifies the signature of a signed PKCS7 payload against embedded signer certificates
  3. VerifyWithChain validates signature trust against a root certificate pool and rejects untrusted pools
  4. Decrypt recovers original plaintext from an EnvelopedData PKCS7 instance using private key and certificate
  5. GetOnlySigner extracts the single leaf signer certificate from a valid SignedData PKCS7 instance
  6. DegenerateCertificate creates a certificate-only PKCS7 structure readable via Parse
