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. dns.Msg.SetTsig configures TSIG pseudo-RR on DNS message with specified key name, algorithm, fudge, and timestamp
  2. dns.TsigGenerate computes HMAC signature and encodes DNS message into authenticated wire format bytes
  3. dns.TsigVerify validates wire format DNS message authenticity against shared secret and confirms integrity
  4. dns.TsigVerify rejects corrupted wire messages or mismatched secrets with validation errors
  5. dns.TsigGenerate and dns.TsigVerify support request MAC chaining for DNS response authentication
