gendsa

GENDSA(1SSL)							      OpenSSL							      GENDSA(1SSL)

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.
