[JDEV] Does Muse support encrypted messaging?

[Chris Chen]

Yes, Muse has support for "working" with encrypted messages.  However, it 
does not support the "encryption" of the message.

What does this mean?  It means that you can call some method like:

It means that there is a message class you can use to attach the encrypted 
data to the message you want to send and also a way to retrieve the 
encrypted message.  However, the message class itself will not do the 
actually encryption of the data for you.  The reasoning behind that is that 
different people use different libraries to do encryption.  Rather than try 
to make everyone conform to a specific library that Muse uses, Muse lets 
you, the developer, decide which encryption library to use.  Once you have 
encrypted the data, it's easy to add it as an XMessage to be sent to the 
remote server and also easy to retrieve it.

Specifically, if you want to send PGP messages, you should instantiate an 
object from PGPEncryptedXMessage.  Once you create it, you can add it to 
the main message (since all X Messages must be inside another message) ... 
a sample code will look something like this.

Jabber jabber = new Jabber();
JabberSession session = jabber.createSession(...);
session.connect(...);
...
...
JabberChatMessage msg = new JabberChatMessage();
msg.setSubject("Test Subject");
msg.setBody("Test Body");
PGPEncryptedXMessage pgpmsg = new PGPEncryptedXMessage();
...
...do you data encryption here...
...
pgpmsg.setPGPMessage("JKLFWIERUOSJKX237492378965<PGP ENCRYPTED DATA>");
msg.addXMessage(JabberCode.XMLNS_X_PGP_ENCRYPTED, pgpmsg);
session.sendMessage(msg);


Hope that helps.  I did put up a beginner's tutorial as well as a 
intermediate user's tutorial for working with the Jabber API.  So you 
should take a look at it.  Also, you should use alpha versions (ie. 0.73a1) 
rather than the stable version.  The alpha version is only there to 
indicate that the Gnutella module is going through some API changes.  The 
Jabber module is not affected at all at this point, so it's safe to use the 
newest version.

If you have any questions and problems regarding Muse, you should contact 
me directly rather than go through JDEV in consideration of the other 
people on this list.

Thanks,
Chris
