How does SSH with private key works?

The client machine that participated in setting up the encryption can decrypt the information using the private key. SSH uses temporal asymmetric keys to exchange symmetric keys, such as during the user authentication process. SSH uses hashing to validate if the data packets come from the source they appear to come from.

Is SSH public key associated with an user?

Provides information about the public Secure Shell (SSH) key that is associated with a user account for the specific file transfer protocol-enabled server (as identified by ServerId ). The information returned includes the date the key was imported, the public key contents, and the public key ID. A user can store more than one SSH public key associated with their user name on a specific server.

How to generate SSH key pair using ssh-keygen?
