Recently, a number of major browser providers started making changes to their support for SHA-1 certificates in SSL, and moving to SHA-2 in response to the weaker security provided by the SHA-1 cryptographic hash algorithm. As a result, on June 1 Webtrends will complete updating its SSL certificates from SHA-1 to SHA-2. This change impacts all Webtrends On Demand clients.
Microsoft announced their deprecation policy on SHA-1 according to which Windows will stop accepting SHA-1 certificates in SSL by 2017. Similarly, Google announced their deprecation policy on SHA-1 according to which Chrome will stop accepting SHA-1 certificates in SSL in a phased way by 2017. Mozilla is also planning to stop accepting SHA-1-based SSL certificates by 2017.
Webtrends has gradually been re-issuing its SHA-1 based SSL certificates with new SHA-2 based certificates to avoid any issues stemming from Google’s Chrome browser updates. Last November, Google started sun-setting its support for SHA-1 in its Chrome browser. The quarterly Chrome browser releases trigger “less than secure” notifications on some SSL certificates using the SHA-1 algorithm, so Webtrends has proactively moved to replace them.
