# ckey var (client)

Source: https://ref.dm-lang.org/client/var/ckey

This is a read-only value that is the canonical form of the player's key (ie the value returned by ckey()). Among other things, this could be used as a unique directory name in a server-side save file for storing player information. See the ckey() proc for an example.
