A keylogger, sometimes called a keystroke logger or keyboard capture, is a type of surveillance technology used to monitor and record each keystroke on a specific computer. Keylogger software is also available for use on smartphones, such as the Apple iPhone and Android devices.

The code opens a file to write the encryption key but doesn't use a context manager (with statement) to ensure that the file is properly closed after writing the key. While the code does close the file explicitly with file.close(), it's safer to use a with statement to handle the file, which will automatically close it even if an exception occurs.
