5 * Disclaimer: This code is presented "as is" without any guarantees.
6 * Details: Performs known-answer tests on the corresponding Blowfish
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.
