Usage
Information
The host keys are required for key-exchange by the SSH server. If the keys are not
found when you enable the server (ip ssh server enable), the keys are
automatically generated.
This command requires user interaction and generates a prompt prior to
overwriting any existing host keys.
NOTE: Only a user with superuser permissions should generate host-keys.
Example
Dell#conf
Dell(conf)#crypto key generate rsa1
Enter key size <1024-2048>. Default<1024>: 1024
Host key already exists. Do you want to replace. [y/n] :y
