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. initializeCryptoEngine configures pkijs to use WebCrypto crypto and subtle engines
  2. createSelfSignedCertificate creates and signs a valid X.509 v3 certificate with subject, issuer, and validity dates
  3. encodeCertificate serializes a Certificate instance into a BER ArrayBuffer schema
  4. decodeCertificate parses a BER ArrayBuffer into a valid Certificate instance with matching properties
  5. verifyCertificate returns true for valid self-signed certificates and false for mismatched issuer signatures
  6. BasicConstraints extension is correctly configured with cA flag and pathLenConstraint
