SSH Commands 393
Example
The following example generates DSA key pairs.
crypto key generate rsa
The crypto key generate rsa Global Configuration mode command generates RSA key pairs.
Syntax
• crypto key generate rsa
Default Configuration
RSA key pairs do not exist.
Command Mode
Global Configuration mode.
User Guidelines
• RSA keys are generated in pairs: one public RSA key and one private RSA key. If the device already has
RSA keys, a warning and prompt to replace the existing keys with new keys are displayed.
• This command is not saved in the device configuration; however, the keys generated by this command
are saved in the private configuration which is never displayed to the user or backed up on another
device.
• RSA keys are saved to the backup master.
• This command may take a considerable period of time to execute.
Example
The following example generates RSA key pairs.
ip ssh pubkey-auth
The ip ssh pubkey-auth Global Configuration mode command enables public key authentication for
incoming SSH sessions. Use the no form of this command to disable this function.
Syntax
• ip ssh pubkey-auth
• no ip ssh pubkey-auth
