Right, and I am running the current version of OpenSSL which, for example, doesn't support SSLv3 or TLSv1.1. > I believe running 'openssl ciphers' Ad that shows ciphers for TLSv1.1 and SSLv3, which is why I am a tad confused. > will list your openssl installation's default cipher list which I am assuming is what SSLCipherSuite set to DEFAULT would use, but I'm guessing.

Intermediate is usually a pretty good starting point for a public web server. Then watching for any cipher-based vulnerabilities that are announced or reported by any vulnerability testing you might have performed. Thanks, I did not find that, I was diving in apache 2.4 examples that were 3+ years old. It's impressive how much faster h2 is than http/1.1. -- Bart, don't use the Touch of Death on your sister. --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscribe@xxxxxxxxxxxxxxxx For additional commands, e-mail: users-help@xxxxxxxxxxxxxxxx
