Goal: find the fastest possible C++ https library that can score an A on the SSLLabs test. Ties broken by ease of use, then by support for websockets.

Initial results (see wiki for latest…):

LIBRARY ab

SCORE
EASE WS? COMMENTS
apache A 3 N need to write a module, apache remains in charge of message loop (unacceptable)
libwebsockets 7 Y
proxygen 7 only easy to build on ubuntu so hasn’t been stood up on my gentoo server yet; huge kitchen sink of helpers
Simple-Web-Server  B 10 Y websockets in a seperate compatible project; may be able to leverage asio to improve score (capped by RC4); no forward secrecy
websocketpp  uses asio, specifies a “modern” mode that only allows TSL1.2
mongoose 3 messy ton of hand-crafted portability C code scared me off
onion looks like a strong C lib
libmicrohttpd GNU c lib, not sure it supports modern algos, check score…
