24=head1 DESCRIPTION
25
26The B<gendsa> command generates a DSA private key from a DSA parameter file
27(which will be typically generated by the B<openssl dsaparam> command).
28
29=head1 OPTIONS
30
31=over 4
32
33=item B<-aes128|-aes192|-aes256|-camellia128|-camellia192|-camellia256|-des|-des3|-idea>
34
35These options encrypt the private key with specified
36cipher before outputting it. A pass phrase is prompted for.
37If none of these options is specified no encryption is used.
38
39=item B<-rand file(s)>
40
41a file or files containing random data used to seed the random number
42generator, or an EGD socket (see L<RAND_egd(3)|RAND_egd(3)>).
43Multiple files can be specified separated by a OS-dependent character.
44The separator is B<;> for MS-Windows, B<,> for OpenVMS, and B<:> for
45all others.
46
47=item B<-engine id>
48
49specifying an engine (by it's unique B<id> string) will cause B<req>
50to attempt to obtain a functional reference to the specified engine,
51thus initialising it if needed. The engine will then be set as the default
52for all available algorithms.
53
54=item B<paramfile>
55
56This option specifies the DSA parameter file to use. The parameters in this
57file determine the size of the private key. DSA parameters can be generated
58and examined using the B<openssl dsaparam> command.

62=head1 NOTES
63
64DSA key generation is little more than random number generation so it is
65much quicker that RSA key generation for example.
