NAME
       openssl-gendsa, gendsa -	generate a DSA private key from	a set of
       parameters

SYNOPSIS
       openssl gendsa [-help] [-out filename] [-aes128]	[-aes192] [-aes256]
       [-aria128] [-aria192] [-aria256]	[-camellia128] [-camellia192]
       [-camellia256] [-des] [-des3] [-idea] [-rand file...]  [-writerand
       file] [-engine id] [paramfile]

DESCRIPTION
       The gendsa command generates a DSA private key from a DSA parameter
       file (which will	be typically generated by the openssl dsaparam
       command).

OPTIONS
       -help
	   Print out a usage message.

       -out filename
	   Output the key to the specified file. If this argument is not
	   specified then standard output is used.

       -aes128,	-aes192, -aes256, -aria128, -aria192, -aria256,	-camellia128,
       -camellia192, -camellia256, -des, -des3,	-idea
	   These options encrypt the private key with specified	cipher before
	   outputting it. A pass phrase	is prompted for.  If none of these
	   options is specified	no encryption is used.

       -rand file...
	   A file or files containing random data used to seed the random
	   number generator.  Multiple files can be specified separated	by an
	   OS-dependent	character.  The	separator is ; for MS-Windows, , for
	   OpenVMS, and	: for all others.

       [-writerand file]
	   Writes random data to the specified file upon exit.	This can be
	   used	with a subsequent -rand	flag.

       -engine id
	   Specifying an engine	(by its	unique id string) will cause gendsa 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.

       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 openssl dsaparam command.

NOTES
       DSA key generation is little more than random number generation so it
       is much quicker that RSA	key generation for example.
