  wince encryption algorithm (An Metet)

This is the secret Ace (and WinAce) encryption algorithm. It is a
combination of a Blowfish derivation and a SHA-1 derivation and it
uses Cipher Block Chaining. I called it AceFish therefore...

This code will only work on machines with Intel byte order! It
shouldnt be too difficult to adapt it for Motorola byte order,
anyway.

==== begin AceFish.h ================================================
ifndef __ACEFISH_H__
define __ACEFISH_H__

typedef unsigned long u32

class AceFish 
    u32 _p18
    u32 _s4256
    u32 _cbc0, _cbc1   // for cipher block chaining

    static void hash(const char str, u32 hash5)

    void encrypt(u32 res_l, u32 res_r, u32 in_l, u32 in_r)
    void decrypt(u32 res_l, u32 res_r, u32 in_l, u32 in_r)

public:
    AceFish(const char password)

    void encrypt(void buffer, size_t bytes)   // (bytes  8) == 0!!
    void decrypt(void buffer, size_t bytes)   // (bytes  8) == 0!!

    void resetCBC() 
        _cbc0 = _cbc1 = 0
    


endif
==== end AceFish.h ==================================================

==== begin AceFish.cpp ==============================================
