Please be aware of the upcoming changes that affect how websites using SHA-1 SSL’s Certs are
displayed in the Chrome browser.

SHA-1 is no longer considered to be sufficiently secure and will be completely phased out in
the next few years. To encourage prompt adoption of more secure algorithms, Starting with
Google Chrome 39, Google start to degrade websites using SHA-1 certificates. The changes start
November 2014.

Initially, the warnings is limited to a “Secure, but minor errors” icon, in the form of a lock
with a yellow triangle. Later versions will display a red crossed-out lock.

SSL Users can prevent a downgraded user experience by following these steps:

– Check which algorithm your SSL Certificate uses.
