オプション
| Tag | Description |
|---|---|
| *-inform DER | PEM * |
| This specifies the input format. The* DER option uses an ASN1 DER encoded form compatible with RFC2459 (PKIX) DSS-Parms that is a SEQUENCE consisting of p, q and g respectively. The PEM form is the default format: it consists of the DER* format base64 encoded with additional header and footer lines. | *-outform DER |
| PEM * | This specifies the output format, the options have the same meaning as the* -inform* option. |
| *-in filename * | This specifies the input filename to read parameters from or standard input if this option is not specified. If the* numbits* parameter is included then this option will be ignored. |
| *-out filename * | This specifies the output filename parameters to. Standard output is used if this option is not present. The output filename should* not* be the same as the input filename. |
| -noout | this option inhibits the output of the encoded version of the parameters. |
| -text | this option prints out the DSA parameters in human readable form. |
| *-C * | this option converts the parameters into C code. The parameters can then be loaded by calling the* *get_dsaXXX() function.
|
| -genkey | this option will generate a DSA either using the specified or generated parameters. |
| *-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. |
| *numbits * | this option specifies that a parameter set should be generated of size* numbits*. It must be the last option. If this option is included then the input file (if any) is ignored. |
| *-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. |

DSAパラメーターの生成は遅いプロセスであるため、同じDSAパラメーターのセットが複数の異なるキーを生成するためによく使用されます。
