Index NAME
gendsa - generate a DSA private key from a set of parameters
SYNOPSIS
openssl gendsa[
-out filename][
-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
- -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 numbergenerator, 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 : forall others.
- -engine id
- specifying an engine (by it's unique id string) will cause reqto attempt to obtain a functional reference to the specified engine,thus initialising it if needed. The engine will then be set as the defaultfor all available algorithms.
- paramfile
- This option specifies the DSA parameter file to use. The parameters in thisfile determine the size of the private key. DSA parameters can be generatedand examined using the openssl dsaparam command.
NOTES
DSA key generation is little more than random number generation so it ismuch quicker that
RSA key generation for example.
