Testing Tomcat 8 SSL using testssl.sh

Configuration:

Apache Tomcat 8.0.18 + JDK 1.8.0_92

APR/Native SSL Connector defined in server.xml:

<Connector
protocol=”org.apache.coyote.http11.Http11AprProtocol”
port=”8443″ maxThreads=”100″
scheme=”https” secure=”true” SSLEnabled=”true”
SSLCertificateFile=”conf/certs/cert.pem”
SSLCertificateKeyFile=”conf/certs/key.pem”
SSLVerifyClient=”optional” SSLProtocol=”TLSv1.1+TLSv1.2″
SSLHonorCipherOrder=”true” SSLCipherSuite=”HIGH:!aNULL:!eNULL:!EXPORT:!3DES:!DES:!RC4:!MD5:!kRSA”/>

Result: ALL OK!

[root@localhost testssl]# ./testssl.sh –quiet localhost:8443
