Three ways to deal with encryption JS

Often encountered in the Web page after logging on the user entered the account number and password through JS encryption, resulting in the simulation of such a site blocked

Here's a little bit. Three ways to solve this problem now

1. Use Python to achieve equal encryption of JS.

2. Log in using selenium emulation.

3. Using Pyexecjs to execute JS file

Test Site: http://bbs.125.la/

The password is encrypted by the Web browser F12 found at login

Further analysis and lookup, found to be named Md5.js? The RFI file is encrypted

Try to use the first method, but found that the content of this file is more complex to convert the program through Python, so discard

Using the second method

#coding =utf-8
Import time
From selenium import Webdriver
Import Selenium.webdriver.support.ui as UI

Start_url = ' http://bbs.125.la/'
Driver = Webdriver. Chrome ()
Driver.maximize_window ()
Driver.implicitly_wait (10)
Driver.get (Start_url)
#通过id方式定位
driver.find_element_by_id (' Ls_username '). Send_keys (U "n***i")
driver.find_element_by_id (' Ls_password '). Send_keys (U "sn*******9")
Driver.find_element_by_class_name (' pn '). Click ()
Time.sleep (3)
Driver.quit ()

This method attempts to log on successfully and tries the third method

Username = ' N***i '

Md5_password = Execjs.compile (open (r "Md5.js"). Read (). Decode ("Utf-8")). Call (' hex_md5 ', password) #md5. js file has been copied to the local
print ' Md5_password: ', Md5_password
R = requests.post (url,headers=headers,data= ' username=%s&password=%s&quickforward=yes&handlekey=ls '% ( Username,md5_password))

Successful output of encrypted password
