+* Details:    Performs known-answer tests on the corresponding SHA1
+	          implementation. These tests do not encompass the full
+	          range of available test vectors, however, if the tests
+	          pass it is very, very likely that the code is correct
+	          and was compiled properly. This code also serves as
+	          example usage of the functions.
