实现原理：导入base64库

一、加密

import base64
 
 
# 加密
username = "admin"
base64_username = base64.b64encode(username.encode('utf-8')).decode()
print(base64_username)
password = "123"
base64_password = base64.b64encode(password.encode('utf-8')).decode()
print(base64_password)

运行结果：

二、解密

import base64

# 加密
username = "CSDN"
base64_username = base64.b64encode(username.encode('utf-8')).decode()
print(base64_username)
password = "123"
base64_password = base64.b64encode(password.encode('utf-8')).decode()
print(base64_password)

# 解密
str1 = base64.b64decode(base64_username.encode('utf-8')).decode()
print(str1)
