NCC Group's Cryptography Services audits our Go TLS 1.3 stack

Cloudflare has released a beta version of its TLS 1.3 implementation, which is based on Go's standard library, crypto/tls. The company engaged NCC Group's Cryptography Services to audit the security of the implementation at the end of 2016. The codebase for Cloudflare's TLS 1.3 can be found on its GitHub page and is a drop-in replacement for crypto/tls, with a go wrapper provided for patching the standard library as needed. Although currently targeted only for internal use, the final goal is to upstream the patches to the Go project so that all users of the Go standard library benefit from it.
