...and per this https://www.openssl.org/blog/blog/2016/08/24/sweet32/

3des is in MEDIUM

Add !3DES

Here's my Ciphers in pound.cfg:

 Ciphers "ALL:!ADH:!EXPORT:!SSLv2:!aNULL:!eNULL:!DES:!MD5:!PSK:!RC4:!DH:!LO=
W:+HIGH:+MEDIUM"

Then I do a sslscan on the pound server and save the data to /tmp/sslscan.o=
ut,

First I check for MD5:

brad.allison@devops-west:/usr/local/devops/bin> grep MD5 /tmp/sslscan.out |=
 wc -l
0

Then I check for RC4:

brad.allison@devops-west:/usr/local/devops/bin> grep RC4 /tmp/sslscan.out |=
 wc -l
0

Then I check for DES:

brad.allison@devops-west:/usr/local/devops/bin> grep DES /tmp/sslscan.out |=
 wc -l
6

brad.allison@devops-west:/usr/local/devops/bin> grep DES /tmp/sslscan.out
    Accepted  TLSv1  112 bits  ECDHE-RSA-DES-CBC3-SHA
    Accepted  TLSv1  112 bits  DES-CBC3-SHA
    Accepted  TLS11  112 bits  ECDHE-RSA-DES-CBC3-SHA
    Accepted  TLS11  112 bits  DES-CBC3-SHA
    Accepted  TLS12  112 bits  ECDHE-RSA-DES-CBC3-SHA
    Accepted  TLS12  112 bits  DES-CBC3-SHA


So why is it allowing DES support when I have !DES in my Ciphers list?
