=pod =head1 NAME dsaparam - DSA parameter manipulation and generation =head1 SYNOPSIS B [B<-inform DER|PEM>] [B<-outform DER|PEM>] [B<-in filename>] [B<-out filename>] [B<-noout>] [B<-text>] [B<-C>] [B<-rand file(s)>] [B<-genkey>] [B] =head1 DESCRIPTION This command is used to manipulate or generate DSA parameter files. =head1 OPTIONS =over 4 =item B<-inform DER|PEM> This specifies the input format. The B option uses an ASN1 DER encoded form compatible with RFC2459 (PKIX) DSS-Parms that is a SEQUENCE consisting of p, q and g respectively. The PEM form is the default format: it consists of the B format base64 encoded with additional header and footer lines. =item B<-outform DER|PEM> This specifies the output format, the options have the same meaning as the B<-inform> option. =item B<-in filename> This specifies the input filename to read parameters from or standard input if this option is not specified. If the B parameter is included then this option will be ignored. =item B<-out filename> This specifies the output filename parameters to. Standard output is used if this option is not present. The output filename should B be the same as the input filename. =item B<-noout> this option inhibits the output of the encoded version of the parameters. =item B<-text> this option prints out the DSA parameters in human readable form. =item B<-C> this option converts the parameters into C code. The parameters can then be loaded by calling the B function. =item B<-genkey> this option will generate a DSA either using the specified or generated parameters. =item B<-rand file(s)> a file or files containing random data used to seed the random number generator. Multiple files can be specified separated by a OS-dependent character. For MS-Windows, the separator is B<;>. For OpenVMS, it's B<,>. For all others, it's B<:>. =item B this option specifies that a parameter set should be generated of size B. It must be the last option. If this option is included then the input file (if any) is ignored. =back =head1 NOTES PEM format DSA parameters use the header and footer lines: -----BEGIN DSA PARAMETERS----- -----END DSA PARAMETERS----- DSA parameter generation is a slow process and as a result the same set of DSA parameters is often used to generate several distinct keys. =head1 SEE ALSO L, L, L, L =cut
