Displays a warning if the site you are browsing is affected by the Heartbleed bug.
Chromebleed was originally created by Jamie Hoyle
with further contributions and collaboration by Tony Alves
Jamie and Tony are the owners and admins of the repository.

There are two mirrors on the Chrome Store.

They are following this repository version tags always. The Stopbleed extension will be the Alpha release of the next version. Google Chrome Store was holding the original extension for review. We are trying to resolve this issue.
Chromebleed version 2.0.0
Stopbleed Version 2.2.0 (Alpha)

What does this do?

Many HTTPS-secured sites on the internet use OpenSSL. Unfortunately, a major vulnerability in OpenSSL was disclosed - known as the Heartbleed bug - yesterday that put hundreds of thousands of servers at risk of compromise.

Whilst some servers have been patched already, many remain that have not been patched. Chromebleed uses a web service developed by Filippo Valsorda and checks the URL of the page you have just loaded. The repository code for the service is hosted here on Github also.

When you browse to a domain affected by Heartbleed, then a Chrome notification will be displayed. It's as simple as that!

Gremlins exist - this was developed rather late at night. Bugs will exist somewhere!
