.SH "NAME"
gendsa \- generate a DSA private key from a set of parameters
.SH "SYNOPSIS"
\fBopenssl\fR \fBgendsa\fR
[\fB\-out filename\fR]
[\fB\-des\fR]
[\fB\-des3\fR]
[\fB\-idea\fR]
[\fB\-rand file(s)\fR]
[\fBparamfile\fR]
.SH "DESCRIPTION"
The \fBgendsa\fR command generates a DSA private key from a DSA parameter file
(which will be typically generated by the \fBopenssl dsaparam\fR command).
.SH "OPTIONS"
.Ip "\fB\-des|\-des3|\-idea\fR" 4
These options encrypt the private key with the \s-1DES\s0, triple \s-1DES\s0, or the
\s-1IDEA\s0 ciphers respectively before outputting it. A pass phrase is prompted for.
If none of these options is specified no encryption is used.
.Ip "\fB\-rand file(s)\fR" 4
a file or files containing random data used to seed the random number
generator, or an \s-1EGD\s0 socket (see the \fIRAND_egd(3)|RAND_egd(3)\fR manpage).
Multiple files can be specified separated by a \s-1OS\s0\-dependent character.
The separator is \fB;\fR for \s-1MS\s0\-Windows, \fB,\fR for OpenVSM, and \fB:\fR for
all others.
.Ip "\fBparamfile\fR" 4
This option specifies the \s-1DSA\s0 parameter file to use. The parameters in this
file determine the size of the private key. \s-1DSA\s0 parameters can be generated
and examined using the \fBopenssl dsaparam\fR command.
.SH "NOTES"
DSA key generation is little more than random number generation so it is
much quicker that RSA key generation for example.
