| 31 | =head1 DESCRIPTION
|
|---|
| 32 |
|
|---|
| 33 | This command generates a DSA private key from a DSA parameter file
|
|---|
| 34 | (which will be typically generated by the L<openssl-dsaparam(1)> command).
|

|

| 41 |
|
|---|
| 42 | Print out a usage message.
|
|---|
| 43 |
|
|---|
| 44 | =item B<-out> I<filename>
|
|---|
| 45 |
|
|---|
| 46 | Output the key to the specified file. If this argument is not specified then
|
|---|
| 47 | standard output is used.
|
|---|
| 48 |
|
|---|
| 49 | =item B<-passout> I<arg>
|
|---|
| 50 |
|
|---|
| 51 | The passphrase used for the output file.
|
|---|
| 52 | See L<openssl-passphrase-options(1)>.

|

| 55 |
|
|---|
| 56 | These options encrypt the private key with specified
|
|---|
| 57 | cipher before outputting it. A pass phrase is prompted for.
|
|---|
| 58 | If none of these options is specified no encryption is used.
|
|---|
| 59 |
|
|---|
| 60 | Note that all options must be given before the I<paramfile> argument.
|
|---|
| 61 | Otherwise they are ignored.

|
|---|
| 73 | The DSA parameter file to use. The parameters in this file determine
|
|---|
| 74 | the size of the private key. DSA parameters can be generated and
|
|---|
| 75 | examined using the L<openssl-dsaparam(1)> command.

| 81 | =head1 NOTES
|
|---|
| 82 |
|
|---|
| 83 | DSA key generation is little more than random number generation so it is
|
|---|
| 84 | much quicker that RSA key generation for example.
