JSON-LD Canonicalization Javascript or Web Service?

There are currently a limited number of libraries for canonicalizing JSON-LD. In particular, for prototyping some DID tools as shell and/or C commands, we can do JSON, RPC and do bitcoin signing but we can't canonicalize it.

I'd like to see a standalone Javascript page and/or RPC web service that you can download locally to your computer that can:

• given a JSON-LD, validate it
• given a JSON-LD Verifiable Claim, validate it
• return a cleaned up JSON-LD
• return a canonicalized JSON-LD ready for signing
• verify a signed JSON-LD object signed with RSA or koblitz

By default we should NOT offering signing via RPC as that is just a bad habit security wise. We can either use other local tools for that (bitcoind signmessage for instance), or sign locally in a separate local javascript file.

Thinking about this further, if this web page or service could also do the bech32 txid <-> txref conversions, and recover a public key from a signature or a the JSON of a rawtransaction, that would be useful.
