Handshake Extractor
===================
This will extract private keys from outgoing handshake sessions, prior
to them being sent, via kprobes. It exports the bare minimum to be
able to then decrypt all packets in the handshake and in the subsequent
transport data session.
Build:
$ make
Run (as root):
# ./extract-handshakes.sh
New handshake session:
LOCAL_STATIC_PRIVATE_KEY = QChaGDXeH3eQsbFAhueUNWFdq9KfpF3yl+eITjZbXEk=
REMOTE_STATIC_PUBLIC_KEY = HzgTY6aWXtuSyW/PUquZtg8LB/DyMwEXGkPiEmdSsUU=
LOCAL_EPHEMERAL_PRIVATE_KEY = UNGdRHuKDeqbFvmiV5FD4wP7a8PqI6v3Xnnz6Jc6NXQ=
PRESHARED_KEY = AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA=
