| =head1 NAME |
| |
| gendsa - generate a DSA private key from a set of parameters |
| |
| =head1 SYNOPSIS |
| |
| B<openssl> B<gendsa> |
| [B<-out filename>] |
| [B<-des>] |
| [B<-des3>] |
| [B<-idea>] |
| [B<-rand file(s)>] |
| [B<-engine id>] |
| [B<paramfile>] |
| |
| =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<-des|-des3|-idea> |
| |
| These options encrypt the private key with the DES, triple DES, or the |
| IDEA ciphers respectively 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 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. |

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