Description of the Intermediate Value Known Answer Test--------------------------------------------------------The test encrypts one plaintext with a variable number of rounds.In ECB encryption mode, the output PTi is the output after the initial key addition and i rounds (a round ends with a keyaddition). As explained in the documentation, in ECB decryption mode there are several definitions of a `round' possible. In orderto make visual inspection more intuitive, we output theintermediate values that correspond with the output of theencryption mode. These values might actually not occur in a practical decryption,especially in an optimised implementation, where various operationsof different rounds are interchanged.This explains also why the Java and the C code output differentfiles for this test.
