WeTV - cKey function

Here's the code (in JavaScript and Python) to make the cKey for downloading stuff from WeTV. This works for encryption version 8.1. Both versions accept the same arguments, first 5 (vid, tm, appVer, guid and platform) are the same as in the call to https://play.wetv.vip/getvinfo. url is optional for JavaScript but required for Python - that's the URL of the page you're on. userAgent, referer, navCodeName, navName and navPlatform are optional, check the code for default values.

Usage

JavaScript

makeCKey(/* arguments here */);
