--- Comment #14 from Mark Thomas <ma...@apache.org> ---
Hmm. I think we need to move the ciphers part of this discussion to the users
list.

With a recent version of OpenSSL, Tomcat's default returns 112 ciphers. Adding
":-DH" reduces that to 83 and adding ":-DH:+ECDH" makes no difference compared
to just to ":-DH". Looking at what "DH" and "ECDH" return on their own, I think
you might want to look at your cipher configuration.

I get an SSL Labs rating of "A" with Tomcat's default ciphers for Tomcat 11 +
Java 21 (OpenSSl and JSSE), Tomcat 8 + Java 11 (OpenSSL and JSSE), Tomcat 8 +
Java 8 (JSSE)

Looking at the results from SSL Labs, adding ":-CBC" looks like something worth
considering.
