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 is displayed.
The maximum supported size for the RSA key is 2048 bits.
This command is not saved in the startup configuration; however, the keys generated by this command are saved in the running
configuration, which is never displayed to the user or backed up to another device.
This command may take a considerable period of time to execute.
Example
The following example generates RSA key pairs.
Console (config)# crypto key generate rsa
