gendsa(1ssl)gendsa(1ssl)NAMEgendsa - Generate a DSA private key from a set of parameters
SYNOPSIS
openssl gendsa [-out filename] [-des] [-des3] [-idea] [-rand filename]
[paramfile]
OPTIONS
Encrypts 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. 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 an OS-dependent character. The separator is a semicolon
(;) for MS-Windows, a comma (,) for OpenVMS, and a colon (:) for all
others. 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.
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).
NOTES
DSA key generation is little more than random number generation, so it
is much quicker than RSA key generation.
