A token generated for human consumption must have the following characteristics:
For example, this is not a good human-usable token:
PY5FAGNNHTCYTAAG

H4NL-N3PW-9RFJ-4TPX
To turn a random token into a human-readable token:
This reduces the entropy in the generated token, but because tokens are easier to read and copy, they can be made longer.
