DESCRIPTIONThe 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 it's unique id string) will cause
req 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.
NOTESDSA key generation is little more than random number generation
so it is much quicker that RSA key generation for example. SEE ALSOdsaparam(1) , dsa(1) , genrsa(1) , rsa(1)
