GENDSA(1)                    OpenSSL                    GENDSA(1)

NAME

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

SYNOPSIS

     openssl gendsa [-out filename] [-aes128] [-aes192] [-aes256]
     [-camellia128] [-camellia192] [-camellia256] [-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

     -aes128|-aes192|-aes256|-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(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.
