Generating/Destroying Key Pairs
This configuration task lets you generate or destroy a key pair. You must generate an RSA and DSA key
pair on the server for an SSH client to log in successfully. When generating a key pair, you will be
prompted to enter the key length in bits, which is between 512 and 2048. The default length is 1024. In
case a key pair already exists, the system will ask whether to replace the existing key pair.
