This week, Google launched Chrome version 42. This enables the complete deprecation of SHA-1 certificates in their browser. That means if your website has an SSL certificate that is using SHA-1, your address bar will look like this:

Sites with SSL certificates that expire between Jan. 1, 2016, and Dec. 31, 2016, and which include a SHA-1-based signature as part of the certificate chain, will be treated as “secure, but with minor errors.”
This does not impact Firefox, Safari, Internet Explorer or Opera. It only affects Google Chrome.
