There is something called Canonical JSON. They take out all the whitespace,
sort keys lexicographically, and only quote the " inside strings. It is
used in the wild by the OLPC project I think.

bencode is an easier to implement protocol that is used in bittorrent and
yields a tiny write-only implementation if all you want to do is get unique
hashes for the subset of JSON used by JWK.
