Apt stores the keys in /etc/apt/trusted.gpg. You can export these keys
with gpg:

gpg --keyring /etc/apt/trusted.gpg -a --export marillat > marillat-key.asc

You can also install the package "debian-keyring" and extract the key
from there. (Use "--keyring /usr/share/keyrings/debian-keyring.gpg" in
the above command.)
