Hello,

I would like to disable low grade encryption in Tomcat.

I have cert that uses 256/1024bit encryption with Apache but same cert with tomcat uses
128/768bit encryption.

The problem is public key size 768 bit that is no more considered secure by Opera.

The problem was discussed here.

http://forum.java.sun.com/thread.jspa?threadID=5247000&messageID=10019756

It happens due to Diffie-Hellman algorythm that is advised to be disabled to avoid the problem.

I did as advised. I added TLS_RSA_WITH_AES_256_CBC_SHA to JAVA_OPTS -Dhttps.cipherSuite
and ciphers attribute in <Connector> in server.xml

Nothing changed after tomcat restart.
I also checked catalina.out and there is no errors or other information about encryption.

It seems Tomcat ignores these settings.

Please, help.

Thank You,
Max
