gendsa - generate a DSA private key from a set of
parameters
SYNOPSIS
openssl gendsa [-out filename] [-des] [-des3] [-idea]
[-rand file(s)] [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.
-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.
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.
