hashlib模块介绍

• 难破解
• 不可逆

hashlib模块中的常用方法

函数名	参数	介绍	举例	返回值
md5	byte	Md5算法加密	hashlib.md5(b'hello')	Hash对象
sha1	byte	Sha1算法加密	hashlib.sha1(b'hello')	Hash对象
sha256	byte	Sha256算法加密	hashlib.sha256(b'hello')	Hash对象
sha512	byte	Sha512算法加密	hashlib.sha512(b'hello')	Hash对象

代码

	# coding:utf-8
	import hashlib
	import time
	base_sigh = 'muke'
	def custom():
	a_timestamp = int(time.time())
	_token = '%s%s' % (base_sigh, a_timestamp)
	# print(_token, type(_token))
	hashobj = hashlib.sha1(_token.encode('utf-8'))
	a_token = hashobj.hexdigest()
	# print(a_token)
	return a_token, a_timestamp
	def b_service_check(token, timestamp):
	_token = '%s%s' % (base_sigh, timestamp)
	b_token = hashlib.sha1(_token.encode('utf-8')).hexdigest()
	if token == b_token:
	return True
	else:
	return False
	if __name__ == '__main__':
	need_help_token, timestamp = custom() # 若只使用一个变量,则此处会生成一个元组传入其变量
	time.sleep(1)
	result = b_service_check(need_help_token, int(time.time()))
	if result == True:
	print('a合法,b服务可以进行帮助')
	else:
	print('a不合法,b不可进行帮助')

base64模块介绍

• 通用型
• 可解密

base64模块的常用方法

函数名	参数	介绍	举例	返回值
encodestring	Byte	进行base64加密	base64.encodestring(b'py')	Byte
decodingstring	Byte	对base64解密	base64.decodestring(b'eGlhb211\n')	Byte
encodebytes(推荐)	Byte	进行bese64加密	base64.encodebytes(b'py')	Byte
decodingbytes(推荐)	Byte	对base64解密	base64.decodebytes(b'eGlhb211\n')	Byte

代码

	# coding:utf-8
	import base64
	replace_one = '%'
	replace_two = '$'
	def encode(data):
	if isinstance(data, str):
	data = data.encode('utf-8')
	elif isinstance(data, bytes):
	data = data
	else:
	raise TypeError('data need bytes or str')
	_data = base64.encodebytes(data).decode('utf-8')
	# print(_data)
	_data = _data.replace('a', replace_one).replace('2', replace_two)
	# print(_data)
	return _data
	def decode(data):
	if not isinstance(data, bytes):
	raise TypeError('data need bytes')
	replace_one_b = replace_one.encode('utf-8')
	replace_two_b = replace_two.encode('utf-8')
	data = data.replace(replace_one_b, b'a').replace(replace_two_b, b'2')
	return base64.decodebytes(data).decode('utf-8')
	if __name__ == '__main__':
	result = encode('hello xiaomu')
	print(result)
	new_result = decode(result.encode('utf-8'))
	print(new_result)
