Facebook Will Stop Supporting SHA-1 in October
June 8, 2015 by Ben Wilson Announcement SSL/TLS
On June 2, 2015, Facebook announced that it would stop supporting Facebook-connected apps that were signed with SHA-1, as of October 1, 2015. “These changes are part of a broader shift in how browsers and web sites encrypt traffic to protect the contents of online communications. Typically, web browsers use a hash function to create a unique fingerprint for a chunk of data or a message. This fingerprint is then digitally signed to prove that a message has not been altered or tampered with when passing through the various servers and systems between your computer and Facebook’s servers.

HTTP/2 Is Speedy and Secure

Since we last wrote about SSL/TLS performance, there has been a lot of activity in the IETF HTTP Working Group, resulting in the February announcement that the next version of HTTP has been approved. This is big news because it means that major SSL/TLS performance improvements are on the way. Background When your browser connects to a website today, it most likely uses the HTTP/1.1 protocol that was defined in 1999 in RFC 2616.

Google to Give Priority Ranking to SSL Enabled Sites
August 21, 2014 by Chris Bailey (Entrust) Announcement Google SSL/TLS
Google’s announcement that it will give priority ranking to SSL enabled sites is a key milestone for increased use of SSL on the Internet. Google announced a change to its ranking algorithm to include use of SSL on the site as a “very lightweight [positive] signal”. Although, this might not have an immediate impact to website owners/operators that are not currently using SSL, this is still an important signal indicating everyone should be prepared to encrypt all their websites if they want to remain relevant.

ICANN’s Accelerated gTLD Delegation Process and How This Impacts Your Organization
December 18, 2013 by Jeremy Rowley Announcement CA/Browser Forum CASC ICANN MITM Mozilla PKI Policy Qualified Revocation SSL/TLS Vulnerability
After the CASC’s previous letter addressing ICANN’s proposal to delegate nearly 2000 new gTLDs for use on the public Internet, ICANN identified and initiated an extensive study on two significant security issues. Now, based on the conclusions of the studies, ICANN is moving forward quickly with the delegation process, delegating more than 30 in the last two months alone. With ICANN ramping up the delegation process, nearly all 2000 will be delegated under the new rules, with only .

CAs Unite
February 14, 2013 by Robin Alden (Sectigo) Announcement CA/Browser Forum CASC SSL/TLS
Today marks an important day for internet security and future SSL enhancements, as the world’s seven largest publicly trusted Certificate Authorities are announcing the formation of the Certificate Authority Security Council. While leading CAs have worked together for years to address security challenges and meet them with evolving and increasingly strict standards and best practices through the CA/Browser Forum and other industry venues, we’ve lacked a union where we can come together and speak with a unified CA voice.
