payload in GenericMessage

[Björn Mayer]

  Hi,

  I was just asking me the following question:
  An ACLMessage is sent within a GenericMessage. Also, an envelope as well  
as a payload are stored within this GenericMessage. Supposed the  
ACLMessage contains sensitive data - can this data (even if partially) be  
reconstructed simply with the help of the payload or the envelope, too?  
What kind of information is stored within this payload? I'm just  
considering security issues and thus would like to know if it would be  
enough to encrypt only the ACLMessage but not the payload...

  I'm thankfull for every single hint,
    Bjorn
