[Bug 1484807] Re: Encryption problems in DC++ 0.851 when connecting to a LUADCH hub

 

Alright, I'm satisfied that OpenSSL as used in DC++ sufficiently
addresses this issue such that I'll add ECDHE-ECDSA-AES128-GCM-SHA256
and ECDHE-ECDSA-AES128-SHA.

However, what additional value does ECDHE-ECDSA-AES128-SHA256 add? It's
CBC, rather than AEAD [1], and thus vulnerable to
http://www.isg.rhul.ac.uk/tls/Lucky13.html unlike ECDHE-ECDSA-AES128
-GCM-SHA256 without, as far as I can tell, being more compatible than
it, as both are TLS v1.2 ciphersuites.

[1] "The following lists give the SSL or TLS cipher suites names from
the relevant specification and their OpenSSL equivalents. ...
TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA256   ECDHE-ECDSA-AES128-SHA256",
