public class CAST128

extends Object

This class tests the correctness of the CAST128 implementation. Generally the test data consist of plain text, cipher text and key data.

The test procedure can be devided into an encrypting and decrypting phase: First the plain data is encrypted according to the selected IDEA-Mode and compared with the given cipher data. The encrypting algorithm works correctly if each block of the cipher data equals to the corresponding block of the encrypted plain data. Following this the cipher data is decrypted and compared with the input plain data. This step prooves the correctness of the decrypting phase.
