How to realize iqiyi Slider encryption in JS reverse

Editor to share with you how to achieve iqiyi slider encryption in JS reverse, I believe most people do not know much about it, so share this article for your reference, I hope you will learn a lot after reading this article, let's learn about it!

First, page analysis

Switch account secret login, grab package, login interface has a passsword,rsa encrypted

Then a few more times, the CAPTCHA will appear.

Second, analysis 1. Split picture restore

You will know how to restore the next canvas breakpoint.

two。 Dynamic AESKey,HMacKey

The data returned by this API will be used, and the submission parameter has an encrypted secure.

Then analyze the secure and drop the breakpoint directly to here.

It involves sha256,rsa, and random numbers.

Random numbers are generated here.

Will be used for the generation of Secure and the submission parameters will be validated

3.cryptSrcData encryption

There are two kinds of encryption, one is to request the encryption of picture parameters, and the other is to request the encryption of sliding verification parameters.

4. Return data decryption
