Dear Ach members,<br>
<br>
when using the nginx server recommendations in the Ach paper, I
cannot get the OpenSSL <i>s_time</i> performance testing to work.
Even the server bettercrypto.org fails. Is this problem due to the
nginx config, or with OpenSSL?<br>
<br>
Running "openssl s_time -connect bettercrypto.org:443 -cipher
AES128-GCM-SHA256 -time 2" returns
"140373676381952:error:14094410:SSL routines:ssl3_read_bytes:sslv3
alert handshake failure:ssl/record/rec_layer_s3.c:1362:SSL alert
number 40" in OpenSSL 1.1.0, and "140416684930936:error:14077410:SSL
routines:SSL23_GET_SERVER_HELLO:sslv3 alert handshake
failure:s23_clnt.c:769:" in 1.0.2h.<br>
<br>
This problem has been found when running from Fedora 24, and also
with other ciphers than just the one mentioned above, as
ECDHE-ECDSA-AES256-GCM-SHA384, ECDHE-ECDSA-AES128-SHA, AES256-SHA,
but not with AES128-SHA.<br>
<br>
I am greatful for insight that would make it possible to use <i>s_time</i>
properly.<br>
<br>
best regards,<br>
