User creation and authentication

[icidasset]

Adds the following functions:

• createAccount
• didJWT
• didKey
• isUsernameAvailable
• updateRoot

Nice this looks really good 👍

I think a few shortcomings in keystore-idb are putting more crypto code here than there really needs to be. I'll see about making those updates soon, shouldn't be too much work

We should still allow byte operations in the keystore-idb interface, but we actually are working with strings here so it's not necessary for this.

So yeah in summary:

• move isRSAKeystore function
• simplify signatures by using keystore interface methods

And this should be good to go 👍

For future reference, if you have to really dig into the internals like this:

  const signed = await operator.signBytes(
    utils.strToArrBuf(`${encodedHeader}.${encodedPayload}`, 8),
    ks.writeKey.privateKey,
    ks.cfg.hashAlg
  )

then it probably means either:

• the abstraction is off and should be fixed in the library
• the library isn't being used quite right and there's probably a better way to do it

these libraries are made by us & primarily for us, so if something seems clunky, ping me and we can change it at the library level 👌

@dholms I just did this instead of adding this isRSA and isECC methods. Is that ok?

[dholms]

Yes that's great 👍
Except... WebCrypto doesn't support Ed25519, it uses NIST Curves (P-256, P-384, P-521). Sooo if we want to support those, we'll need to figure out magic bytes & what not for them on the server...

We may want to have CryptoSystem.ECC return null until we get that set up server-side. The ts-sdk always generates RSA keys unless the user overrides it

[icidasset]

Ohhh ok, woops. I assumed ECC was the same as ED 😅 Yeah, we should discuss this later. In the meantime, will remove the ecc/ed stuff.

[dholms]

Yeah too many acronyms, it's all so confusing 😅

ED is a type of ECC. But multiformats are supposed to be completely self-describing so each ECC curve needs it's own ✨ magic bytes ✨

[icidasset]

Added hooks here ☝️

Sweet this is lookin good! 🎉 🎉
