Introducing s2n-tls, a New Open Source TLS Implementation | Amazon Web Services
AWS Security Blog Introducing s2n-tls, a New Open Source TLS Implementation February 22, 2022: s2n has been renamed to s2n-tls. See details. At Amazon Web Services, strong encryption is one of our standard features, and an integral aspect of that is the TLS (previously called SSL) encryption protocol. TLS is used with every AWS API and is also available directly to customers of many AWS services i

How POODLE Happened — Indistinguishable from Random
Bodo Möller, Thai Duong, and Krzysztof Kotowicz have just broken the internet again with POODLE[20], a new and devastating attack against SSL. POODLE, an acronym for Padding Oracle On Downgraded Legacy Encryption, permits a man-in-the-middle attacker to rapidly decrypt any browser session which utilizes SSL v3.0 — or, as is generally the case, any session which can be coerced into utilizing it.

We have used a number of patches on top of OpenSSL for many years. Some of them have been accepted into the main OpenSSL repository, but many of them don’t m
