openssl-gendsa - generate a DSA private key from a set of parameters


openssl gendsa [-help] [-out filename] [-passout arg] [-aes128] [-aes192] [-aes256] [-aria128] [-aria192] [-aria256] [-camellia128] [-camellia192] [-camellia256] [-des] [-des3] [-idea] [-verbose] [-quiet] [-rand files] [-writerand file] [-engine id] [-provider name] [-provider-path path] [-propquery propq] [paramfile]


This command generates a DSA private key from a DSA parameter file (which will be typically generated by the openssl-dsaparam(1) command).


Print out a usage message.
Output the key to the specified file. If this argument is not specified then standard output is used.
The passphrase used for the output file. See openssl-passphrase-options(1).
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.

Print extra details about the operations being performed.
Print fewer details about the operations being performed, which may be handy during batch scripts and pipelines.
See "Random State Options" in openssl(1) for details.
See "Engine Options" in openssl(1). This option is deprecated.
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.
See "Provider Options" in openssl(1), provider(7), and property(7).


DSA key generation is little more than random number generation so it is much quicker that RSA key generation for example.

The -engine option was deprecated in OpenSSL 3.0.
