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 command).
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 encryption is used.
-randfile(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 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
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.
