Security Commands 1084
User Guidelines
The key string is the public key of the specified type (RSA or DSA) generated
by the administrator. The administrator will need access to both the public
and private key on the host to log in without authenticating via password.
Enclose the key string in quotes.
DSA is considered less secure than RSA. Use of RSA is suggested.
Use the key-string row command to specify which SSH public key you will
configure interactively next. To complete the interactive command, you must
enter key-string row with no characters.
Examples
The following example shows how to enter a public key string for a user called
"bob."
console(config)#crypto key pubkey-chain ssh user-key bob rsa
console(config-pubkey-chain)#Key-String "ssh-rsa
