* Details: Performs known-answer tests on the corresponding AES

implementation. These tests do not encompass the full
|
|
range of available test vectors and are not sufficient
|

for FIPS-140 certification. 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.
