模块 hashlib, hmac

import hashlib
# 主要提供SHA1, SHA224, SHA256, SHA384, SHA512, MD5
tmp = hashlib.md5()
tmp.update(b'hello')
print(tmp.hexdigest())
tmp.update('ddd的ddd'.encode(encoding='utf-8'))
print(tmp.hexdigest())

import hmac
# 双层加密，速度比较快，用于消息加密

htmp = hmac.new(b"meirong", b"hinimix")
print(htmp.digest())
print(htmp.hexdigest())
