Shorter key lengths allow faster operation, but also mean diminished security. The cert and autorun parameters only use RSA key types. You can choose either RSA or DSA key types when using the crypto key generate ssh command. Note that, unlike the use of the switch public key in an SSH client application, the format of a client public key used by the switch does not include the client's IP address. Spaces are allowed within the key to delimit the key's components. If you add more than one client public key to a file, terminate each key (except the last one) with a. The key must be one unbroken ASCII string. See Example of a correctly formatted public key. The private key is usually stored in a password-protected file on the local host the public key is stored in another file and is not protected. SSH clients that support client public-key authentication normally provide a utility to generate a key pair.

If you do not allow secondary SSH login (operator) access via local password the switch will refuse other SSH clients. If you use this feature, only the clients whose public keys are in the client public-key file you store on the switch will have SSH access to the switch over the network. In this case, only clients with a private key corresponding to one of the stored public keys can gain access to the switch using SSH. This requires storing an ASCII version of each client's public key (without babble conversion, or fingerprint conversion) in a client public-key file that you create and TFTP-copy to the switch. To provide the optional, opposite service-client public-key authentication to the switch-you can configure the switch to store up to 10 public keys for authenticating clients. When configured for SSH operation, the switch automatically attempts to use its own host public key to authenticate itself to SSH clients. SSH client public-key authentication notes
