Private Key
Also: secret key file, PEM key
The secret half of a key pair, which proves identity or decrypts data and must never leave its owner.
In more detail
A private key in a log, repository or model output (often starting with -----BEGIN PRIVATE KEY-----) lets anyone impersonate the owner. If one is exposed, treat it as stolen: revoke and replace it rather than only deleting the exposure.
