python

python3中，导入hashlib库

import hashlib


m = hashlib.md5()  # 写法1
m.update(b'a123456')
n = m.hexdigest()
print(n)

a = hashlib.md5(b'a123456').hexdigest()  # 写法2，最常见的
print(a)

b = hashlib.new('md5', b'a123456').hexdigest()  # 写法3
print(b)

对中文加密

data = '你好'
nn = hashlib.md5(data.encode(encoding='UTF-8')).hexdigest()  # 对中文进行加密，需先转码
print(nn)
