This Go program is a simple keylogger that monitors keyboard input and logs it to a file. Below is an explanation of its components:
- GetAsyncKeyState: This function checks the state of a specified virtual key. It is used to detect key presses.
- GetKeyboardState: This function retrieves the status of all virtual keys. It is used to check the current state of the keyboard.
- MapVirtualKeyW: This function translates a virtual-key code into a scan code or character value. It is used to translate virtual key codes to Unicode.
- ToUnicode: This function translates the specified virtual-key code and keyboard state to the corresponding Unicode character or characters.
The program continuously loops to monitor key presses and writes the corresponding Unicode characters to a log file located at C:\temp\keylogger.txt.
To run the program, simply compile it using the Go compiler and execute the resulting binary. The program will start monitoring keyboard input and logging it to the specified file.
