For the passphrases, use the passphrases used earlier.Thinking about TLS (Transport Layer Security, the succesor of Secure Socket Layer, SSL) and WebLogic and Oracle HTTP Server, allways gave me Cold Water Fear. You have to create keystores with keys, wallets, certificate signing requests, import signed and trusted certificate chains. Not to mention the configuration of WebLogic and OHS.
Now, creating keystores with the Java Keytool turns out not that hard. And generating the Certificate signing requests and importing the certificates are also a walk in the park, nowadays. The internet world is full of example so I'm not going to do that here.
But lately, our Service Bus developers found that they needed to replace the configured demo identity and trust key stores with Custom Stores. But this broke the connection between the AdminServer and the Nodemanagers, resulting in TLS/SSL Handshake errors. By default, the nodemanagers work with the demo-identities when running in TLS.
This drove us to work out an infrastructural configuration of TLSin our FMW environments, in a  way that the SB developers can extend that with their certificates.
In this article I want to describe how to configure TLSin Weblogic using the KeyStore Service, and also how to reconfigure the nodemanagers to have them running TLS using the custom stores.

Keystores and the KeyStore Service (KSS)

When implementing in TLS in Fusion MiddleWare 12c you have the choice to use the new KeyStore Service for creating keys and certificates directly in the KSS, or the Java Key Tool.
Until now WebLogic preferred a Java Key Store (JKS) for storing certificates. This is a file that functions as a vault to store your keys and certificates savely. You can use the commandline tool Keytool that is delivered with the JDK. But there are several graphical tools, like Portecle, that can make your encrypting life even more simple.
