Encryption keys, being purely random, are not copyrightable. (In light of recent events, this raises the question of artisanal human-created keys.) Distributing keys probably violates DMCA section 1201 though.

Spotify's offline playback DRM hinges on a HMAC key that's a human-readable phrase, based on a certain lyric. I'm curious whether it's just a fun easter egg, or if there's some kind of legal basis for the choice.
