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.
- -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.
- 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.
- -rand files, -writerand file
- See "Random State Options" in openssl(1) for details.
- -engine id
- 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.
- -provider name
- -provider-path path
- -propquery propq
- 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.
