public class Test {

out[i] = (byte) (a | b);

}
}

  //填上代码
}
}

public static void main(String[] args) throws Exception {
int password = 0xea154884;
byte[] buf1 = { -110, -65, -125, 82, -38, -15, 77, -14, 88, 32, -5,
122, 83, 86, 69, 74, 46, 53, -62, -89, 59, 18, 86, 78, 26, 41, };
byte[] buf2 = new byte[buf1.length];
decode(buf1, buf2, password);
System.out.println(new String(buf2, "GBK"));
}

}


------解决方案--------------------
就是要解密回来吧
根据加密代码反过来实现就可以了

Java code

public static void decode(byte[] in, byte[] out, int password) {
    int len = in.length;

    int seed = password ^ 0xd6445ad8;
    for (int i = 0; i < len; ++i) {
        byte a = (byte)(in[i] & 0x1f);
        byte b = (byte)(in[i] & 0xe0);
        a = (byte)(((a << 3) ^ seed) & 0xf8);
        b = (byte)((((((int)b) << (13-5)) ^ seed) >> 13) & 0x07);
        out[i] = (byte) (a | b);
        seed = ((seed ^ in[i]) * 5393887 + in[i]);
    }
}
