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.
