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

SYNOPSIS
       openssl gendsa [-out filename] [-des] [-des3] [-idea] [-rand file(s)]
       [-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 com-
       mand).

OPTIONS
       -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 encryp-
	   tion is used.

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

       -engine id
	   specifying an engine (by it’s unique id string) will cause req 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 parame-
	   ters 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.
