第三方python 加密库 --- cryptography

1,安装依赖

pip install cryptography

2，生成秘钥

from cryptography.fernet import Fernet
#秘钥#随机生成秘钥  cipher_key = Fernet.generate_key()
cipher_key ='pXVAHabI4HADuM-fyVogxwV5rHRN1pZe-QQ3yM9ZvPg='

3,加密（‘123‘为要加密的对象）

a = Fernet(cipher_key).encrypt(“123”.encode()).decode()
print(a)

运行结果：
gAAAAABcmrvXiWdU9ICuUGDQoYgEQuqv0lL8BpQWRot3gJJJIGAwJlgDOKrmx8JH6mpbTfG9AdUTfUZ0eHNrXXDohCSXb87RqA==

4，解密：

b = Fernet(cipher_key).decrypt(a.encode()).decode()
print(b)

运行结果：
123
