Configuring Key Pairs
The SSH server’s key pairs are for generating session keys and for SSH clients to authenticate the
server. The SSH client's key pairs are for the SSH server to authenticate the SSH clients in publickey
authentication mode. Both RSA and DSA key pairs are supported.
As different clients may support different public key algorithms, the key pairs negotiated between the
server and clients may be different. Therefore, you need to generate both RSA and DSA key pairs on
the server to ensure that clients can log in to the server successfully.
You can specify an algorithm for publickey authentication as needed.
Generating key pairs
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. If the key pair already exists, the system will ask whether to
overwrite it.
