DESCRIPTION
       This command is used to manipulate or generate DSA parameter files.

OOPPTTIIOONNSS
       -iinnffoorrmm DDEERR||PPEEMM
           This specifies the input format. The DDEERR 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 DDEERR format base64 encoded with
           additional header and footer lines.

       -oouuttffoorrmm DDEERR||PPEEMM
           This specifies the output format, the options have the same meaning
           as the -iinnffoorrmm option.

       -iinn ffiilleennaammee
           This specifies the input filename to read parameters from or
           standard input if this option is not specified. If the nnuummbbiittss
           parameter is included then this option will be ignored.

       -oouutt ffiilleennaammee
           This specifies the output filename parameters to. Standard output
           is used if this option is not present. The output filename should
           nnoott be the same as the input filename.

       -nnoooouutt
           this option inhibits the output of the encoded version of the
           parameters.

       -tteexxtt
           this option prints out the DSA parameters in human readable form.

       -CC  this option converts the parameters into C code. The parameters can
           then be loaded by calling the ggeettddssaaXXXXXX(()) function.

       -ggeennkkeeyy
           this option will generate a DSA either using the specified or
           generated parameters.

       -rraanndd ffiillee((ss))
           a file or files containing random data used to seed the random
           number generator, or an EGD socket (see RANDegd(3)).  Multiple
           files can be specified separated by a OS-dependent character.  The
           separator is ;; for MS-Windows, ,, for OpenVMS, and :: for all others.

       nnuummbbiittss
           this option specifies that a parameter set should be generated of
           size nnuummbbiittss. It must be the last option. If this option is
           included then the input file (if any) is ignored.

       -eennggiinnee iidd
           specifying an engine (by it's unique iidd string) will cause rreeqq 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.

NNOOTTEESS
       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.
