When crawling contact number 58 city rental information found crawl '13823661900' corresponding to the content is 'Long grain ration grain ration Cangxiebocang owl Long Run Run'

Encryption should look font, font encryption usually is a web page modified the default character set encoding, webpage definition loaded on a Web page font file as font style, you can correctly display numbers, but in the source code on the same binary numbers due not load custom font files to default by a computer coding has become garbled.

The solution: find the font file, file mapping relationship analysis, the general style font files are added as part of the encrypted font.

You can see from the chart, uncheck fangchan-secret style, the show has become part of the contents of encrypted content we actually crawling, so this is most likely fangchan-secret encrypted font file, the search page source code 'fangchan-secret' encrypted file to find the font, as shown below: Code in the figure below, the font file is encrypted after passing through the base64 placed inside js, wherein the encrypted portions (content within the two red bars) taken , n will be used to take out the contents (or directly copy down). Each time the page refreshes, the mapping order in the font file encryption may change, so it is best if the order changes observed under the map.

Here is the code:

import base64

You can see the final results are printed out and the numbers we see on the page is the same, the decryption is successful ~ well done!
