Are your WebSmart and Presto programs getting SSL certificate errors?

If your WebSmart and Presto programs use SSL (Secure Sockets Layer) then you most likely installed an SSL certificate on your server. Browsers recently started phasing out a common method of encryption (called SHA-1), which may be causing errors in browsers when users visit your site. These errors typically occur in Chrome and Firefox, even when the certificate is valid.

Please note that if your certificate is valid, the connection is still encrypted. However, you should upgrade your certificate to circumvent these errors because they can impact whether or not users trust your site. SHA-1 is now 20 years old and is considered a weak encryption algorithm. Its use on the internet has been deprecated since 2011 and is being replaced with SHA-256 (SHA-2).

Affected Browsers

Chrome
Google began producing warnings about the obsolete encryption algorithm in Chrome version 39 (September 2014). You can read more about it here.

FireFox
Mozilla began issuing errors in browser versions released in early 2015 and onward. Version 38.0.5 behaves this way. You can read more about it here.

Microsoft
Microsoft has a commitment to completely end support for SHA-1 in their browsers by January 2017, which is consistent with the general industry decision.

Please refer to the links below for more information. Some of the references link to SSL certificate providers (Thawte and Semantic) so the information is reliable.
