NAME
openssl-gendsa, gendsa - generate a DSA private key from a set of
parameters
SYNOPSIS
openssl gendsa [-out filename] [-aes128] [-aes192] [-aes256]
[-camellia128] [-camellia192] [-camellia256] [-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
command).
OPTIONS
-aes128|-aes192|-aes256|-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(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 others.
-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.
