What is an SSH key
A public SSH key is one component of a cryptographic key pair used by the SSH (Secure Shell) protocol.
It essentially provides access authorization for the SSH network protocol, which enables authenticated and encrypted remote communications between devices over an unsecured network. It is essential for secure file transfers, network management and remote access to operating systems, thanks to authentication based on public and private key cryptography.
