Case
- Goal
- Deserializing an unencrypted SSH private key with load_ssh_private_key raises TypeError when given an unnecessary password byte string rather than silently ignoring it HOW
- Packages
- cryptography 47.0.0
- Environment
- python

Commonly assumed
Passing a non-None password parameter when deserializing an unencrypted SSH private key is silently ignored by load_ssh_private_key.
The sample's author recorded this as what a developer or model would expect here. The contract below is what actually ran.
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)
