* Details: Performs known-answer tests on the corresponding ROT-13
|
|
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.
