MD5 (Message-Digest algorithm 5) is a widely used, partially insecure[1] cryptographic hash function with a 128-bit hash value. As an Internet standard (RFC 1321), MD5 has been employed in a wide variety of security applications, and is also commonly used to check the integrity of files. An MD5 hash is typically expressed as a 32 digit hexadecimal number.

利用CSocket实现远程桌面功能。程序有点复杂，主要是CSocket的运用。 实现思路主要是：先将远程桌面捕获发回本地，然后在对话框中显示，将本地鼠标、键盘的动作变成命令输入，再发送到远程主机执行（实际上这一步是模拟出鼠标和键盘的操作），最后将远程桌面再次捕获发回本地，在对话框中显示出来。这样也就实现了系统自带的远程桌面的功能。-Use CSocket remote desktop functionality. Process a bit complicated, mainly the use of CSocket. To achieve the main idea is: first issued back to the local Remote Desktop Capture, and then in the dialog box shows that the local mouse and keyboard moves into a command input, and then sent to the remote host implementation (actually, this step is to simulate the mouse and keyboard operation), and finally re-captured the remote desktop back to the local, in the dialog box is displayed. This also enables the system comes with remote desktop functionality.
