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 com-
    mand).

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 encryp-
   tion is used.

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

    -engine id
   specifying an engine (by it's unique id string) will cause req 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.
