 Description
 -----------
 
-:program:`ndnsec-key-gen` generates a key pair for the specified *identity* and
-sets the generated public key as the identity's default key.
-:program:`ndnsec-key-gen` will also create a signing request for the generated key.
-The signing request will be written to the standard output in base64 encoding.
+Generate a public/private key pair for the specified *identity* and set the newly generated
