Hello Mark, I have a question for SSL Support - BIO and NIO. It is mention that useServerCipherSuitesOrder can be used with Java 8 only So is there a way (in java 7 and BIO and NIO support ) or another parameter we can use with "ciphers" to force client follow the order of ciphers.
The JSSE implementation guide documents that the client tells the server which cipher suites it has available, and the server chooses the best mutually acceptable cipher suite. I am facing an issue where TLS_RSA_WITH_AES_256_CBC_SHA is being chosen from all other available ECDHE and DHE suites. -Utkarsh On Fri, May 20, 2016 at 4:51 PM, Mark Thomas <ma...@apache.org> wrote: > On 20/05/2016 12:18, Utkarsh Dave wrote: > > Hi Mark - Thanks. > > SSLHonorCipherOrder, cna it be configured on Tomcat ? > > There would not have been much point telling you about a configuration > option you could not use would there? > > It sounds like you need to spend a few minutes looking over the TLS > configuration options for the APR/native HTTP connector: > > > http://tomcat.apache.org/tomcat-7.0-doc/config/http.html#SSL_Support_-_APR/Native > > Mark > > > > > > -thanks > > > > On Fri, May 20, 2016 at 4:42 PM, Mark Thomas <ma...@apache.org> wrote: > > > >> On 20/05/2016 12:04, Jan Dosoudil wrote: > >>> Hi, > >>> do you have Java Cryptography Extension (JCE) Unlimited Strength > >>> Jurisdiction Policy Files installed? > >> > >> Irrelevant.
