Алгоритмы шифрования

Есть у кого часть кода/готовая программа из имеющихся алгоритмов шифрования ниже(на любом языке программирования):
1. Алгоритм Grand Cru
2. Hierocrypt L1
3. Hierocrypt 3
4. HPC
5. ICE
6. Iceberg
7. FROG
8. Kasumi
9. Khazad
10. Loki 97
11. Magenta
12. RC2
13. RC5
14. RC6


Имеется часть кода от RC5 но не могу никак скомпилировать.

Выдаёт кучу ошибок. Посмотрите пожалуйста. Если заработает киньте готовую программу, а то завтра уже зачёт(
