Reaching toward universal TLS SNI

The past few years have seen a dramatic increase in client support for TLS SNI a technology standard that makes HTTPS much more scaleable. While early 2014 saw fewer than 85% of HTTPS requests being sent by clients supporting TLS SNI, many Akamai customers today now see client TLS SNI usage...

Buggy Domain Validation Forces GoDaddy to Revoke Certs

GoDaddy has revoked, and begun the process of re-issuing, new SSL certificates for more than 6,000 customers after a bug was discovered in the registrar’s domain validation process. The bug was introduced July 29 and impacted fewer than two percent of the certificates GoDaddy issued from that dat...

Half of Chrome Pageloads are HTTPS

First it was Mozilla, and now Google is the latest to confirm that encryption is inching closer toward becoming a standard building block for websites and web applications. Google reported yesterday that more than half of pages loaded on desktop versions of the Chrome browser are being done so ov...

openssl: EVP_EncryptUpdate overflow

An integer overflow flaw, leading to a buffer overflow, was found in the way the EVPEncryptUpdate function of OpenSSL parsed very large amounts of input data. A remote attacker could use this flaw to crash an application using OpenSSL or, possibly, execute arbitrary code with the permissions of t...

Free SSL Sparks Unprecedented Growth in Encrypted Traffic

If recent telemetry from Mozilla is indeed representative of the Internet, then it would appear that half of all traffic in transit is encrypted, a more than 10 percent jump from last December. The emergence of free Certificate Authorities such as Let’s Encrypt, and similar gratis HTTPS certifica...
