From 021cf733c637927de4f2988f8cf3df84b2bca9d2 Mon Sep 17 00:00:00 2001 From: Bertrand Jacquin Date: Sun, 1 Dec 2019 19:54:36 +0000 Subject: [PATCH] ssl: server-side: allow multiple version of TLS boost::asio::ssl::context is created using specifically TLSv1.2, which blocks the ability to use superior version of TLS like TLSv1.3. Filtering is also made specially later in the code to remove unsafe version for TLS such SSLv2, SSLv3 etc.. This change is removing double filtering to allow TLSv1.2 and above to be used. testssl.sh 3.0rc5 now reports the following (please note monerod was built with USE_EXTRA_EC_CERT): $ ./testssl.sh --openssl=/usr/bin/openssl \ --each-cipher --cipher-per-proto \ --server-defaults --server-preference \ --vulnerable --heartbleed --ccs --ticketbleed \ --robot --renegotiation --compression --breach \ --poodle --tls-fallback --sweet32 --beast --lucky13 \ --freak --logjam --drown --pfs --rc4 --full \ --wide --hints 127.0.0.1:38081 Using "OpenSSL 1.1.1d 10 Sep 2019" [~80 ciphers] on ip-10-97-15-6:/usr/bin/openssl (built: "Dec 3 21:14:51 2019", platform: "linux-x86_64") Start 2019-12-03 21:51:25 -->> 127.0.0.1:38081 (127.0.0.1) <<-- rDNS (127.0.0.1): -- Service detected: HTTP Testing protocols via sockets except NPN+ALPN SSLv2 not offered (OK) SSLv3 not offered (OK) TLS 1 not offered TLS 1.1 not offered TLS 1.2 offered (OK) TLS 1.3 offered (OK): final NPN/SPDY not offered ALPN/HTTP2 not offered Testing for server implementation bugs No bugs found.
