4 | |||
5 | gendsa - generate a DSA private key from a set of parameters | ||
6 | |||
7 | =head1 SYNOPSIS | ||
8 | |||
9 | B<openssl> B<gendsa> | ||
10 | [B<-out filename>] | ||
11 | [B<-des>] | ||
12 | [B<-des3>] | ||
13 | [B<-idea>] | ||
14 | [B<-rand file(s)>] | ||
15 | [B<paramfile>] | ||
16 | |||
17 | =head1 DESCRIPTION | ||
18 | |||
19 | The B<gendsa> command generates a DSA private key from a DSA parameter file | ||
20 | (which will be typically generated by the B<openssl dsaparam> command). | ||
21 | |||
22 | =head1 OPTIONS | ||
23 | |||
24 | =over 4 | ||
25 | |||
26 | =item B<-des|-des3|-idea> | ||
27 | |||
28 | These options encrypt the private key with the DES, triple DES, or the | ||
29 | IDEA ciphers respectively before outputting it. A pass phrase is prompted for. | ||
30 | If none of these options is specified no encryption is used. | ||
31 | |||
32 | =item B<-rand file(s)> | ||
33 | |||
34 | a file or files containing random data used to seed the random number | ||
35 | generator, or an EGD socket (see L<RAND_egd(3)|RAND_egd(3)>). | ||
36 | Multiple files can be specified separated by a OS-dependent character. | ||
37 | The separator is B<;> for MS-Windows, B<,> for OpenVSM, and B<:> for | ||
38 | all others. | ||
39 | |||
40 | =item B<paramfile> | ||
41 | |||
42 | This option specifies the DSA parameter file to use. The parameters in this | ||
43 | file determine the size of the private key. DSA parameters can be generated | ||
44 | and examined using the B<openssl dsaparam> command. | ||

48 | =head1 NOTES | ||
49 | |||
50 | DSA key generation is little more than random number generation so it is | ||
51 | much quicker that RSA key generation for example. | ||
