Ok, by the way, if you are  working on IAX encryption, you might want  
to look at the way that SNMP does the AES padding.
Roughly, it allows you to send packets that are the same length as the  
cleartext - i.e. without padding the message to 32 byte boundaries.

I'm not totally convinced it is applicable to IAX, but it may be.
