The crypto key generate rsa global configuration command generates RSA key pairs.

Syntax

crypto key generate rsa

Default Configuration

RSA key pairs do not exist.

Command 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 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
