=head1 NAME |
|
|
|
gendsa - generate a DSA private key from a set of parameters |
|
|
|
=head1 SYNOPSIS |

B<openssl> B<gendsa> |
|
[B<-out filename>] |
|
[B<-aes128>] |
|
[B<-aes192>] |

|
[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<-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. |
