Is "Message Key Negotiation" in Agent API for Java optional or necessary?

[WilkoGrey]

Hy, 

I want to use the Authentication Agent API 8.6 for Java Developer and in the Developer Guide is a section "Configure Message Key Negotiation".

Is this feature "Message Key Negotiation" optional or must i add the mentioned security provider into the JDK?

I ask this question, because i have had already a lot of problems with a IBM JDK and configuring the security providers in the "java.security" file and want to avoid this step when possible.

Thanks for any help.

It is necessary. The API will throw key negotiation and credential mismatch errors otherwise.

Message key negotiation is to generate the shared symmetric key used to encrypt authentication requests.
