NAME
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.
