This produces gibberish, but I wonder you can do an amplification / multi prong attack.

Something like:

- Have <ek-dk> produce an "extract-key" phrase and "dns-tx-key" phrase

- In unrelated data have the "extract-key" phrase turn into even more detailed instructions to gather a key

- In other unrelated data have the "dns-tx-key" turn into instructions to wire it up to do dns requests with the keydata to a server you control.
