Hi, i need to fully understand the IPSec Phase 1 negotiation. now, I break this to 3 steps: 1) Algorithm negotiations. 2) Key Exchange Data 3) Identification
I'm using wireshark to invastigate the process and so far I fully understands the 1st part (Algorithm Negotiations). My current problem lies in the 2 nd part: Key Exchange Data.
The Algorithms in use are AES-CBC-256bit, Pre-shared key, MD5 & 1024 bit Group. The "ISAKMP Payload"->"KeyExchange Payload"->"KeyExchangeData" is beyond me... I have no clue what it is.. an MD5'ed pre-shared key? is it encrypted?...
