programming help (encryption etc.)

[shyguy]

as a project i am adding security to a chat room application all in java...

i already have the basic chat server and client, but i need to create a seperate java application to integrate with it to add security.

so i basically need to set it up so that all communications are encrypted, so outside eavesdroppers cant understand them. i have to implement authentication so that only verified users can access the chat service. the method used was going to be a based on a simplified version of the Kerberos protocol. was going to omit the Kerberos ticket server from this for the time being.

any help here would be muchly appreciated... source code of a working example would be great...

TLS (commonly known as SSL) is really probably the answer to your problems. Much easier than Kerberos to implement, you should be able to use some of the SSL capabilities in Java to run your chat discussions over SSL.

Generally speaking, whatever protocol you're using between the clientsand server would simply get passed over SSL... pretty simple.

(Sorry no reply sooner... haven't been 'round much lately!)
