UDPack is an extensible generic UDP packet obfuscator. The purpose of this application is to sit in the path of a UDP data stream, and obfuscate, deobfuscate or otherwise modify the packets.
Python 3.4 or above is required, since this script uses the
asynciolibrary. Currently there are no other dependencies.
Warning: It must be stressed that the purpose of this application is obfuscation , not encryption . Many design decisions have been (and will be) deliberately made against best practices in cryptography, so in all likelihood the obfuscation methods will not resist crypto analysis. DO NOT rely on the obfuscation for confidentiality of your data!!!
At this stage the script includes the following "packers" (obfuscation methods):
- Straight through: no obfuscation
- Shuffle: shuffle the order of data bytes in each packet
A "packer" is a particular implementation of obfuscation method, usually obfuscating packets travelling upstream and deobfuscating packets travelling downstream. An "unpacker" is the same thing, implemented in the opposite direction.
raw data obfuscated data raw data UDP Client ---------- Packer =============== Unpacker ---------- UDP server upstream ==> <== downstream
Implementing new packers and unpackers
In most cases, to implement a new packer, simply inherit from
unpackmethods. To implement the corresponding unpacker, inherit from
UDPackUnpackerMixInand the completed packer.
