- =head1 DESCRIPTION
- The B<gendsa> command generates a DSA private key from a DSA parameter file
- (which will be typically generated by the B<openssl dsaparam> command).
- =head1 OPTIONS
- =over 4
- =item B<-help>
- Print out a usage message.
- =item B<-out filename>
- Output the key to the specified file. If this argument is not specified then
- standard output is used.
- =item B<-aes128>, B<-aes192>, B<-aes256>, B<-aria128>, B<-aria192>, B<-aria256>, B<-camellia128>, B<-camellia192>, B<-camellia256>, B<-des>, B<-des3>, B<-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.
- =item B<-rand file...>
- A file or files containing random data used to seed the random number
- generator.
- Multiple files can be specified separated by an OS-dependent character.
- The separator is B<;> for MS-Windows, B<,> for OpenVMS, and B<:> for
- all others.
- =item [B<-writerand file>]
- Writes random data to the specified I<file> upon exit.
- This can be used with a subsequent B<-rand> flag.
- =item B<-engine id>
- Specifying an engine (by its unique B<id> string) will cause B<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.
- =item B<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 B<openssl dsaparam> command.
- =back
- =head1 NOTES
- DSA key generation is little more than random number generation so it is
- much quicker that RSA key generation for example.
