openssl gendsa

generate a DSA private key from a set of parameters 

openssl command


SYNOPSIS

openssl gendsa [-out filename] [-des] [-des3] [-idea] [-rand file(s)] [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 

encrypts 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) 

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

paramfile 

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.
