How to download a CRX file from the Chrome web sto

Question

I'd like to download the .crx file of an extension from webstore, I use fiddler to analyze the network request when I install an extension from webstore and got it.
For example, for the extension: https://chrome.google.com/webstore/detail/bjclhonkhgkidmlkghlkiffhoikhaajg
the download link is:

https://clients2.googleusercontent.com/crx/download/OgAAADQ_Loe5gfVPF2OUaB35tvex-NKlmA8V4K5YlWuvLCknMH7egLLmnMoFuCZePl_idE1GMf8jZC2KbjQqyyLDoDAAxlKa5eDp-z9frOppHWtQsRU3-iGrrrrA/extension_1_7_11.crx
Now I'm wondering if there is a universal method for get .crx of an extension, the problem is how did Google encryption

bjclhonkhgkidmlkghlkiffhoikhaajg

into

any idea will be helpful.

Answer 1

Also, I recommend to try this website http://crxextractor.com. Here you can download an extension by it's Chrome Webstore URL and extract it's source code in the browser, no additional software required, and everything get done in a click or two.

Answer 2

This is a lower-tech way of doing it than to use fiddler, and I realize this is three years old now, but I always look to see if someone else has solved the problem. So I found someone did, and I just used their solution several times successfully. Their solution is an extension that can download other extensions, called Give Me CRX:

Answer 3

None of the manually ways in this post works for me so i searched for a URL to download the extension direct. Find this and works perfect for me.

https://clients2.google.com/service/update2/crx?response=redirect&prodversion=49.0&x=id%3D###EXTENSION_ID###%26installsource%3Dondemand%26uc

You must replace ###EXTENSION_ID### with the extension id from the chrome shop. Its part of the URL.

Example Google Translate Extension:

https://clients2.google.com/service/update2/crx?response=redirect&prodversion=49.0&x=id%3Daapbdbdomjkkjkaonfhkkikfgjllcleb%26installsource%3Dondemand%26uc
