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
DellEMC(conf)# crypto key generate rsa
Enter key size <1024-2048>. Default<1024> :
Host key already exists. Overwrite (y/n)?y
Generating 1024-bit SSHv2 RSA key.
