Support for jwk / multicodec / did:key #20

Open OR13 opened 4 years ago

OR13 commented 4 years ago

The DID Core spec allows the use of JWK keys for all verification methods... because of this, they are a better interoperability target than PEM.

If the representations supported here: https://github.com/w3c-ccg/lds-jws2020

Don't cover the cryptographic primitives needed for IPID, I would be glad to know that.

It seems that libp2p crypto has no support for jwk. Ideally the support should be added there to avoid having adoc integrations here.

We have some "on going"/"to start" efforts regarding crypto in libp2p:

We can eventually get jwk keys to the crypto roadmap. @OR13 Can you start by creating an issue in the libp2p/js-libp2p-crypto module?

does lib p2p support multicodec / base58 ? Its possible that is also a better future facing target than PEM.

I recently implemented support for did:key with secp256k1, and added support for cross conversion from base58 / hex / jwk here: https://github.com/transmute-industries/did-key.js

Seems like from https://github.com/libp2p/js-libp2p-crypto#cryptokeys

Ideally did:ipid would support RSA, Ed25519 and Secp256k1 + NIST Curves as JWKs / base58... base58 might be more in the spirit of IPFS.

There is an intermediary representation for keys which makes support for DIDs easier, here is an example for secp256k1: https://github.com/transmute-industries/did-key.js/blob/master/packages/did-key-secp256k1/src/Secp256k1KeyPair.ts

I would expect ipid to rely on something like this wrapped around libp2p/js-libp2p-crypto.

I opened: https://github.com/libp2p/js-libp2p-crypto/issues/177

I'm not sure about the best way to layer these things, but I'd personally love to see less PEM and JWK and more multicodec.
