由于支付宝安全输入控件，如同其他众多安全控件方法一样，采用驱动方法劫持了IRP。这导致无法向其输入字符，传统的方法无论是发送WM_Char或者是WM_Keydown消息，还是Keybd_event和SendInput均对其无效。



笔者摸索出了通过直接读取$60,$64硬件端口来操作键盘，模拟输入的方法。



由于在Ring3下，由于Windows的保护机制，我无法直接操作硬件端口，所以我们需要构造一个驱动，或者使用著名的WinIo库。



这里给出我封装好的使用WinIo库进行模拟击键输入的代码，此段代码只在PS/2下测试通过，未在USB情况下测试。本代码主要封装了ASCII码或字符与键盘扫描码之间转换。

-Email security as a result of input controls, as many other methods of security control as a hostage-driven approach adopted IRP. This has led not to enter characters, both traditional methods WM_Char or send WM_Keydown news, or Keybd_event and its SendInput are null and void.



I explored through direct read $ 60, $ 64 hardware keyboard ports, analog input methods.



Ring3 because, as the Windows of the protection mechanism, I can not directly operate the hardware port, so we need to construct a drive, or the use of well-known WinIo library.



Given a good package here, I use the keyboard to simulate the Treasury WinIo enter the code, This code only in the PS/2 under the test is passed, no test in the USB case. The main package of the code of the ASCII code or character and switch between the keyboard scan code.
