NAME

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

SYNOPSIS

       openssl gendsa [-help] [-out filename] [-aes128] [-aes192] [-aes256] [-aria128] [-aria192]
       [-aria256] [-camellia128] [-camellia192] [-camellia256] [-des] [-des3] [-idea] [-rand
       file...]  [-writerand file] [-engine id] [paramfile]

DESCRIPTION

       The gendsa command generates a DSA private key from a DSA parameter file (which will be
       typically generated by the openssl dsaparam 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.

       -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.

       -rand file...
           A file or files containing random data used to seed the random number generator.
           Multiple files can be specified separated by an OS-dependent character.  The separator
           is ; for MS-Windows, , for OpenVMS, and : for all others.

       [-writerand file]
           Writes random data to the specified file upon exit.  This can be used with a
           subsequent -rand flag.

       -engine id
           Specifying an engine (by its unique id string) will cause gendsa to attempt to obtain
           a functional reference to the specified engine, thus initialising it if needed. The
           engine will then be set as the default for all available algorithms.

       paramfile
           This option specifies 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 command.

NOTES

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