Keyfile to decrypt system over ssh

Hi,

I have successfully setup a fully encrypted system LVM on LUKS using this great guide.

Since it is a headless system, I prefer to unlock it remotely. The running setup using tinyssh is done as explained here.
Everything works smooth, I can login using ssh, type my password and the system starts.

My question now is whether I can also use a keyfile. It is straightforward to add a keyfile to the LUKS. Is there a way to provide the keyfile from my personal computer over ssh to the tinyssh server to unlock and boot the system?

I am using arch linux on all systems, everything is fully updated.

Many thanks for any hints.
