NAME gendsa - generate a DSA private key from a set of parameters
-out filename] [
-rand file(s)] [
-engine id] [
gendsa command generates a DSA private key from a DSA parameter file (which will be typically generated by the
openssl dsaparam command).
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.
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.
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.
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.
