Foreword
The latest write Taobao hot plug Taobao sign series which involves encryption algorithms, where bloggers share before finding algorithm and the algorithm using the tutorial and modification. In the hope to help more people, I welcome you to join AC Q group: 468 458 543, within the group of major sites from time to time to share encryption algorithm oh
Tutorial
Taobao sign need to pass four parameters
tooken, time timestamp, appKey key, data data
tooken generally in the cookie _m_h5_tk the
timestamps generated their own free
appKey find yourself
data is generally a period of json
following look at Taobao official submission parameter

Let's look at the math is not official and the same?
1 sign("6620e884e98009cf556bf8a8915e2395","1565235881353","12574478",{"keyword":"热卖","ppath":"","loc":"","minPrice":"","maxPrice":"","ismall":"","ship":"","itemAssurance":"","exchange7":"","custAssurance":"","b":"","clk1":"cab6e9b4b36f8ff6eec6cca229c4e7e7","pvoff":"","pageSize":"100","page":"0","elemtid":"1","refpid":"mm_26632258_3504122_32538762","pid":"430673_1006","featureNames":"spGoldMedal,dsrDescribe,dsrDescribeGap,dsrService,dsrServiceGap,dsrDeliver, dsrDeliverGap","ac":"w9x7FaK+sywCAXZxAYrp1Abf","wangwangid":"qq2757189408","catId":""}) 2 //计算结果 3 730b9faf873a581477639ebba0397e5c
And you can see that Taobao is the same as the official
