Fortunately, there is only one encryption parameter. The search method is good. Take the encryption parameter and search it globally. The parameter value is the id tag of the password input box.

Nine times out of ten, that's it. Let's go to the next breakpoint. After the breakpoint, I debugged all the way down to the following function in a few steps

Click in to have a look. The code seems to have found the code encrypted by JS.

Step by step down, straight to the return value, found to be empty

Continue to go down, the breakpoint goes back to the original judgment function, and then enters another encryption function

Look at the code, all encrypted variables are related to the object CryptoJS, so the key is to find the relevant code defined by this object. Continue to single-step debugging

Two steps later, the definition of CryptoJS is found. It's very simple, copy it all.

Crack

It's easy to find the encrypted JS, copy it, and debug it locally.
