They are, but apple have the keys : https://thehackernews.com/2016/01/apple-icloud-imessages.htm...
So basically, they could be in clear text, it's pretty much the same.
Please see this link[1], Apple explains exactly how keys are stored in their datacenters (Hint: it is not in clear text). They use HSM's which destroy the user's key after 10 failed attempts.
