Notification payloads IV (Repost)
Could someone help me with that or pint me a place to find how it's
done?
I can't find a way to make it work. Only works in Quaick mode but not in
Main mode.
Heeelp!

Subject: Notification payloads IV
How is the IV computed for notification messages in IKE Phase I?
I know in phase II it's computed:
"using the hash of a concatenation of the last Phase I CBC block
concatenated and the message id in the ISAKMP header" (RFC 2409 Apendic B)
However, I'm not really sure how to do it for Phase I when
encryption is applied (messages 5 and 6) and an error is found.
Is it explained somewhere?
