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