Wireshark-dev: [Wireshark-dev] [Patch] : IPsec

From: Frédéric Roudaut <frederic.roudaut@xxxxxxx>

Date: Wed, 20 Dec 2006 16:01:06 +0100

Hi,

This is a patch for the IPsec dissector in order to update/correct thefollowing points:


- Fixes for TWOFISH-CBC with keylen 128 bits.
- Add CAST5-CBC
- Add HMAC-RIPEMD160-96
- Fixes for AES-CTR that was completely broken

- Code Update : Encryption, Authentication are now in separatedfunctions. It seems easier to add new algorithms. Just modify the ESPContext function and enhance the Encrypt or Authentication functionaccording to the algorithm.- The IV field is no more decrypted. (Instead it is set in the cipherobject)

- the authentication field remains in the main tree that is not decrypted.


Best Regards,

ps: In attachment you will also get a dump with all the availablealgorithms for FuzzTesting. It also contains a packet (a tunnel oftunnel of ..) with all the different algorithms and a Configure fileto set the keys/algorithms.The packets have been generated using an Extension to Scapy I have doneto handle IPsec.See http://roudaut.frederic.free.fr/data/scapysec/doc/scapysec.html ifneeded
