172specifying an engine (by it's unique \fBid\fR string) will cause \fBreq\fR
173to attempt to obtain a functional reference to the specified engine,
174thus initialising it if needed. The engine will then be set as the default
175for all available algorithms.

178This option specifies the \s-1DSA\s0 parameter file to use. The parameters in this
179file determine the size of the private key. \s-1DSA\s0 parameters can be generated
180and examined using the \fBopenssl dsaparam\fR command.
