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.
