Key Extractor
=============

This will extract the symmetric ChaCha20Poly1305 session keys from the kernel
for a WireGuard interface, for use in making packet dissectors.


Build:
    $ make

Run (as root):
    # ./extract-keys INTERFACE

Output:
    REMOTE_KEY_ID SENDING_KEY
    LOCAL_KEY_ID RECEIVING_KEY

Example:
    # ./extract-keys wg0
