This extension allows you to validate checksum of web hosted binaries before than download. Extension requires a getsum server to be available.

Usage:
See a simple listen/server example at:
https://github.com/getsumio/getsum

Extension also allows you to use 127.0.0.1 / localhost ports.

After your server is running visit extension options page first, set your hostname value i.e. http://127.0.0.1/8088 and other preferences and save.

Then any page right click on a download link and select GetSum then select desired algorithm.

If you want to validate checksum of this file then first select text and right click so extension will check if any selected text exist and if it is valid it will use it for comparation.
