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.

Contract
- load_ssh_private_key raises TypeError when a password byte string is passed for an unencrypted SSH private key rather than silently ignoring the unneeded password.
- assert 'not encrypted' in str(err).lower()
- assert loaded_key.public_key().public_bytes(Encoding.OpenSSH, PublicFormat.OpenSSH) == private_key.public_key().public_bytes(Encoding.OpenSSH, PublicFormat.OpenSSH)
