5 gendsa - generate a DSA private key from a set of parameters
27 The B<gendsa> command generates a DSA private key from a DSA parameter file
28 (which will be typically generated by the B<openssl dsaparam> command).
36 Print out a usage message.
38 =item B<-out filename>
40 Output the key to the specified file. If this argument is not specified then
41 standard output is used.
43 =item B<-aes128|-aes192|-aes256|-camellia128|-camellia192|-camellia256|-des|-des3|-idea>
45 These options encrypt the private key with specified
46 cipher before outputting it. A pass phrase is prompted for.
47 If none of these options is specified no encryption is used.
49 =item B<-rand file(s)>
51 a file or files containing random data used to seed the random number
52 generator, or an EGD socket (see L<RAND_egd(3)>).
53 Multiple files can be specified separated by an OS-dependent character.
54 The separator is B<;> for MS-Windows, B<,> for OpenVMS, and B<:> for
59 specifying an engine (by its unique B<id> string) will cause B<gendsa>
60 to attempt to obtain a functional reference to the specified engine,
61 thus initialising it if needed. The engine will then be set as the default
62 for all available algorithms.
66 This option specifies the DSA parameter file to use. The parameters in this
67 file determine the size of the private key. DSA parameters can be generated
68 and examined using the B<openssl dsaparam> command.
74 DSA key generation is little more than random number generation so it is
75 much quicker that RSA key generation for example.
