3.4.1 2025-04-03 OPENSSL-GENDSA(1SSL)
Description
This command generates a DSA private key from a DSA parameter file (which will be typically generated by
the openssl-dsaparam(1) command).
History
The -engine option was deprecated in OpenSSL 3.0.
Name
openssl-gendsa - generate a DSA private key from a set of parameters
Notes
DSA key generation is little more than random number generation so it is much quicker that RSA key
generation for example.
Options
-help
Print out a usage message.
-outfilename
Output the key to the specified file. If this argument is not specified then standard output is used.
-passoutarg
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.
-randfiles, -writerandfile
See "Random State Options" in openssl(1) for details.
-engineid
See "Engine Options" in openssl(1). This option is deprecated.
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.
-providername-provider-pathpath-propquerypropq
See "Provider Options" in openssl(1), provider(7), and property(7).
