Re: [Ipsec-tools-devel] Cryptography

[Marcelo M. <mar...@gm...>]

Thanks for the answers.
But I think I was not very clear.
I have an AES implemented in hardware and I call it using C.  I just want to
make a branch in the ipsec-tools to call my AES instead of the one that
comes with ipsec-tools.
I'm changing the parser and I want to know what all the things I have to
change in setkey and racoon.
For example: which function calls the cryptographyc algorithm?
I'm looking at the struct m_sa. I have to use it to make the branch?

Thanks in advance!
