No pain,No gain

역시 extable 키 값을 각각 지정 해주시면 됩니다. ^^아래의 값은 임시 적입니다.~

const unsigned char extable[4] = {0x1D, 0x1D, 0x1B, 0xF1};

void IntToByte(int num, unsigned char* value)

{

    value[0] = ((unsigned char)(num >> 24)) ^ extable[0];

    value[1] = ((unsigned char)(num >> 16)) ^ extable[1];

    value[2] = ((unsigned char)(num >> 8)) ^ extable[2];

    value[3] = ((unsigned char)(num)) ^ extable[3];

}

void IntToByteNon(int num, unsigned char* value)

{

    value[0] = ((unsigned char)(num >> 24));

    value[1] = ((unsigned char)(num >> 16));

    value[2] = ((unsigned char)(num >> 8));

    value[3] = ((unsigned char)(num));

}

int ByteToInt(unsigned char* value)

{

    int retV = 0;

    retV = (((value[0] & 0xFF) ^ extable[0]) << 24) |

    (((value[1] & 0xFF) ^ extable[1]) << 16) |

    (((value[2] & 0xFF) ^ extable[2]) << 8) |

    ((value[3] & 0xFF) ^ extable[3]);

    return retV;

}

int ByteToIntNon(unsigned char* value)

{

    int retV = 0;

    retV = (((value[0] & 0xFF)) << 24) |

    (((value[1] & 0xFF)) << 16) |

    (((value[2] & 0xFF)) << 8) |

    ((value[3] & 0xFF));

    return retV;

}

- (int) setInt_XOR:(int)value {

    IntToByte(value,_changeBuf);

    return ByteToIntNon(_changeBuf);

}

- (int) getInt_XOR:(int)value {

    memset(_changeBuf, 0x00, 4);

    IntToByteNon(value,_changeBuf);

    return ByteToInt(_changeBuf);

}

아래의 extable 은 각 고유 키를 넣어 주면 됩니다. ^^

byte[] extable = {0x1D, 0x1D, 0x1B, 0x3F} ;

byte[] _changeBuf = {0,0,0,0} ;

void Start() {

Debug.Log(intToXOR(1000));

int kTemp = intToXOR(1000);

Debug.Log(xorToINT(kTemp));

Debug.Log(intToXOR(10000));

kTemp = intToXOR(10000);

Debug.Log(xorToINT(kTemp));

}

{

    value[0] = (byte)((num >> 24) ^ extable[0]);

    value[1] = (byte)((num >> 16) ^ extable[1]);

    value[2] = (byte)((num >> 8) ^ extable[2]);

    value[3] = (byte)(num ^ extable[3]);

}

private int ByteToIntNon(byte[] value)

{

    int retV = 0;
