Igor Galić commented on TS-2400:
--------------------------------
[~bcall] with your recent work around SSL, do you have an opinion on this as
well?
A recommendation from
https://bettercrypto.org/static/applied-crypto-hardening.pdf is to set the
cipher suite to
{code}
EDH+CAMELLIA:EDH+aRSA:EECDH+aRSA+AESGCM:EECDH+aRSA+ \
SHA384:EECDH+aRSA+SHA256:EECDH:+CAMELLIA256:+AES256:+CAMELLIA128 \
:+AES128:+SSLv3:!aNULL:!eNULL:!LOW:!3DES:!MD5:!EXP:!PSK:!SRP:! \
DSS:!RC4:!SEED:!ECDSA:CAMELLIA256 -SHA:AES256 -SHA:CAMELLIA128 -SHA \
:AES128 -SHA
{code}
while disabling both SSLv2 and SSLv3.
I'm afraid Leif is right, at least in regard to the SSL Protocols, that this is
a compatibility break and needs to go into 5.0.x

> RC4-SHA:AES128-SHA:DES-CBC3-SHA:AES256-SHA:ALL:!aNULL:!EXP:!LOW:!MD5:!SSLV2:!NULL
> {code}
> Worse yet, it still has RC4 in there, along with some other bad defaults. RC4

> Perfect Forward Secrecy, which means we should also advocate OpenSSL >=
