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] [-rand files] [-writerand file] [-engine id] [-provider name]
       [-provider-path path] [-propquery propq] [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.  Otherwise they are
           ignored.

       -verbose
           Print extra details about the operations being performed.

       -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.

       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.

       -provider name
       -provider-path path
       -propquery propq
           See "Provider Options" in openssl(1), provider(7), and property(7).

NOTES

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