A pass phrase is prompted for. +If none of these options is specified no encryption is used. + +=item B<-rand file(s)> + +a file or files containing random data used to seed the random number +generator, or an EGD socket (see L<RAND_egd(3)|RAND_egd(3)>). +Multiple files can be specified separated by a OS-dependent character. +The separator is B<;> for MS-Windows, B<,> for OpenVMS, and B<:> for +all others. + +=item B<-engine id> + +specifying an engine (by it's unique B<id> string) will cause B<req> +to attempt to obtain a functional reference to the specified engine, +thus initialising it if needed. The engine will then be set as the default +for all available algorithms. + +=item B<paramfile> + +This option specifies the DSA parameter file to use. The parameters in this +file determine the size of the private key. DSA parameters can be generated +and examined using the B<openssl dsaparam> command. + +=back + +=head1 NOTES + +DSA key generation is little more than random number generation so it is +much quicker that RSA key generation for example. + +=head1 SEE ALSO + +L<dsaparam(1)|dsaparam(1)>, L<dsa(1)|dsa(1)>, L<genrsa(1)|genrsa(1)>, +L<rsa(1)|rsa(1)> + +=cut |
