GENDSA(1)                           OpenSSL                          GENDSA(1)



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

SYNOPSIS
       openssl gendsa [-out filename] [-des] [-des3] [-idea] [-rand file(s)] [-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
       -des|-des3|-idea
           These options encrypt the private key with the DES, triple DES, or the IDEA
           ciphers respectively before outputting it. A pass phrase is prompted for.  If
           none of these options is specified no encryption is used.

       -rand file(s)
           a file or files containing random data used to seed the random number
           generator, or an EGD socket (see RAND_egd(3)).  Multiple files can be specified
           separated by a OS-dependent character.  The separator is ; for MS-Windows, ,
           for OpenVMS, and : for all others.

       -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.
