What is the name of the parameter file for SSH keys?

The parameter file for SSH keys is commonly referred to as the "identity file." This file is crucial because it contains the private key associated with your SSH identity. When you authenticate to a remote server using SSH, the application looks for this identity file to securely connect you without requiring a password each time.

The term "identity" emphasizes the role of this file in verifying your identity during authentication. The identity file provides a secure method to log into systems, ensuring that only users with the correct private key can establish a connection.

In contrast, while a credential file may store various types of credentials, it doesn't specifically relate to SSH key storage. Similarly, a key file is a more generic term that could refer to many types of files containing cryptographic keys but is not the standard term used for SSH. The config file generally contains configuration settings rather than being a specific container for key identity information.
