A pass phrase is prompted for. If none of these options is specified no encryption is used. .IP "\fB\-rand file(s)\fR" 4 .IX Item "-rand file(s)" a file or files containing random data used to seed the random number generator, or an \s-1EGD\s0 socket (see \fBRAND_egd\fR\|(3)).

The separator is \fB;\fR for MS-Windows, \fB,\fR for OpenVMS, and \fB:\fR for all others. .IP "\fB\-engine id\fR" 4 .IX Item "-engine id" specifying an engine (by its unique \fBid\fR string) will cause \fBgendsa\fR 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. .IP "\fBparamfile\fR" 4 .IX Item "paramfile" 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" .IX Header "NOTES" \&\s-1DSA\s0 key generation is little more than random number generation so it is much quicker that \s-1RSA\s0 key generation for example. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBdsaparam\fR\|(1), \fBdsa\fR\|(1), \fBgenrsa\fR\|(1), \&\fBrsa\fR\|(1)
