+gendsa - generate a DSA private key from a set of parameters

+
+=head1 DESCRIPTION
+
+The B<gendsa> command generates a DSA private key from a DSA parameter file
+(which will be typically generated by the B<openssl dsaparam> command).
+
+=head1 OPTIONS
+
+=over 4
+
+=item B<-aes128|-aes192|-aes256|-camellia128|-camellia192|-camellia256|-des|-des3|-idea>
+
+These options encrypt the private key with specified
+cipher before outputting it. 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 its unique B<id> string) will cause B<gendsa>
+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.

+=head1 NOTES
+
+DSA key generation is little more than random number generation so it is
+much quicker that RSA key generation for example.
