=pod =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<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<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. =back =head1 NOTES DSA key generation is little more than random number generation so it is much quicker that RSA key generation for example. =head1 SEE ALSO L<dsaparam(1)|dsaparam(1)>, L<dsa(1)|dsa(1)>, L<genrsa(1)|genrsa(1)>, L<rsa(1)|rsa(1)> =cut
