When trying to crawl the Shanxi Window APP, I found that the JSON data is not a direct JSON structure. It seems to be encrypted. Is there a way to parse the original content?

response

After checking some information, it seems that some companies will encrypt the data transmitted at both ends of the APP. How should I judge which encryption method is used? And is there a way to decrypt the data? Thank you so much.

Answer 1

You need to know the encryption method to decrypt, and brute force cracking is a bit difficult.

To know the encryption method, you can decompile the APP and check the encryption method in the code.

Answer 2

This on the screenshot looks like it should be base64 encoded.
