NAME
openssl-gendsa - generate a DSA private key from a set of parameters
SYNOPSIS
openssl gendsa [-help] [-out filename] [-passout arg] [-aes128] [-aes192] [-aes256] [-aria128] [-aria192] [-aria256] [-camellia128] [-camellia192] [-camellia256] [-des] [-des3] [-idea] [-verbose] [-quiet] {- $OpenSSL::safe::opt_r_synopsis -} {- $OpenSSL::safe::opt_engine_synopsis -}{- $OpenSSL::safe::opt_provider_synopsis -} [paramfile]
DESCRIPTION
This command generates a DSA private key from a DSA parameter file (which will be typically generated by the openssl-dsaparam(1) 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.
- -passout arg
-
The passphrase used for the output file. See openssl-passphrase-options(1).
- -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.
Note that all options must be given before the paramfile argument.
- -verbose
-
Print extra details about the operations being performed.
- -quiet
-
Print fewer details about the operations being performed, which may be handy during batch scripts and pipelines.
{- $OpenSSL::safe::opt_r_item -}
{- $OpenSSL::safe::opt_engine_item -}
- paramfile
-
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(1) command.
{- $OpenSSL::safe::opt_provider_item -}
NOTES
DSA key generation is little more than random number generation so it is much quicker that RSA key generation for example.
