Communication using Secure Shell keys

SSH authentication is possible not only using an account and password, but also by means of an SSH key pair.

This type of authentication should be preferred above all when programming automated procedures because a password then does not need to be coded in plain text.

Security-relevant actions

As administrator you can store SSH key (pairs).

You can provide additional protection for the stored keys by means of “passphrases”.
The key management associated with this is described in detail in the next section.
