Java Analysis of Java Code How to Generate a MAC Token with Secret
You need to explore the work of the app on Android.
The server releases the token 829db7e2-6472-48d1-b951-6cef4680cbc6 (TokenSn), and the client to send the request generates some TokenSnMac, in the 6 digit format. For the token above, the client generated the token 481634.
The client generates such a token every a few minutes if sending the same numbers within 2-3 minutes the server rejects the request. Also, if you just send random 6 numbers, the server will definitely reject the request.
The code is present, but it is decompilated with apk, and it is extremely difficult for me to read it.
In a word, reverse engineering.
