Python之MD5加密

Python 3下MD5加密

            <span class="hljs-preprocessor"># 在python3中使用hashlib模块进行md5操作</span>

import hashlib

# 待加密信息
str = ‘this is a md5 test.’

# 创建md5对象
hl = hashlib.md5()

# Tips
# 此处必须声明encode
# 若写法为hl.update(str) 报错为： Unicode-objects must be encoded before hashing
hl.update(str.encode(encoding=‘utf-8’))

print(‘MD5加密前为：’ + str)
print(‘MD5加密后为：’ + hl.hexdigest())
