| Tea256 | | public class Tea256 extends AbstractSymmetricKey implements SymmetricKey(Code) | | Implementation of Tiny Encryption Algorithm, modified to use longs
instead of ints. SO the key is now four longs, or 256 bits, and the
encryption/decryption proceeds 16 bytes at a time instead of 8.
The number of rounds has been retained at 32.
