 Description
 -----------
 
-:program:`ndnsec-cert-gen` takes a signing request as input and issues an
-identity certificate for the key in the signing request. The signing request
-can be created with :program:`ndnsec-key-gen` and can be re-generated with
-:program:`ndnsec-sign-req`.
+This command takes a signing request as input and issues an identity certificate for
+the key contained in the signing request.
+A signing request is generated automatically by :program:`ndnsec-key-gen` for any new
+key, or it can be manually created for an existing key with :program:`ndnsec-sign-req`.
 
-By default, the default key is used to sign the issued certificate.
+Unless specified otherwise, the default key is used to sign the issued certificate.
 
-*file* is the name of a file that contains the signing request. If *file* is
-"-", the signing request is read from the standard input.
+*file* is the name of a file that contains the signing request.
+If *file* is "-", the signing request is read from the standard input.
 
-The generated certificate is written to the standard output in base64 encoding.
