[sr-dev] New Kamailio module Obfuscate

[Daniel-Constantin Mierla]

Hello,

I looked at the code and my conclusion was that the name is a bit confusing.

While indeed you can do obfuscation using some embedded language or 
other meanings from the config file, the module itself doesn't do 
anything related. It executes an event route for network packet in/out.

Such functionaly is of course useful, just to remind the given example 
with obfuscation. But I think a better name to reflect the behaviour 
should be given.

Maybe obfuscate should be a module that implement some algorithms for 
obfuscations, like you mentions:
- simply compressing (gz)
- compressing and encapsulation as body in a http request/reply
- itv

My proposal would be:
- either rename the module or embed in another module (e.g., corex) what 
was developed for these event route execution. The event route name 
should be related to network reception/transmission (e.g., network:msg). 
Also the is_obfuscated_msg() should be something like is_incoming()
- have a new module obfuscate to implement some algorithm as proof of 
concept (e.g., gzip -- i guess plenty of code from gzcompress module is 
very useful just to take from there). Then others may contribute more, 
as they have new ideas or from what you listed (http ecapsulation is at 
least interesting, considering many allow port 80 and inspect for http).

Of course, these are my opinions, so the discussion can go on for 
deciding on how to proceed.

Cheers,
Daniel
