The main feature I wanted from Django REST Framework was the automatic API documentation.

Then I found that there was a standard to document APIs, using JSON (or YAML, an extension of JSON) called Swagger.

And there was a web user interface for Swagger APIs already created. So, being able to generate Swagger documentation for an API would allow using this web user interface automatically.

	nilReq, err := newTestSignedRequestV4(http.MethodPut, getPutPolicyURL("", nilBucket),
		0, nil, "", "", nil)
	if err != nil {

            assertTrue(s1.isEmpty());
            // isBlank will fail if sub_authority is null, so we skip that check for s1

Create a file called `cert.cnf` with the content below. This file contains all of the information necessary to generate a certificate using `certtool.exe`:
