The SSH protocol utilizes community key cryptography for authenticating hosts and consumers. The authentication keys, termed SSH keys, are produced using the keygen method.

— tend to be applied rather than passwords, as they provide a safer approach to connecting to remote Linux servers. As Section of the Protected Shell cryptographic community protocol, SSH keys also enable consumers to securely conduct community solutions above an unsecured community, including providing text-primarily based commands into a remote server or configuring its expert services.

SSH crucial pairs are two cryptographically secure keys that may be used to authenticate a client to an SSH server. Each key pair is made of a public essential and A non-public important.
