Usage

import { EdDSASigner } from 'iso-signatures/signers/eddsa'
import * as EdDSA from 'iso-signatures/verifiers/eddsa'
import { Resolver } from 'iso-signatures/verifiers/resolver'

const message = new TextEncoder().encode('hello world')
const resolver = new Resolver({
  ...EdDSA.verifier,
})
const signer = await EdDSASigner.generate()
const signature = await signer.sign(message)
const verified = await resolver.verify({
  signature,
  message,
  ...signer,
})

import { EdDSASigner } from 'iso-signatures/signers/eddsa'
import * as EdDSA from 'iso-signatures/verifiers/eddsa'
import * as ECDSA from 'iso-signatures/verifiers/ecdsa'
import * as RSA from 'iso-signatures/verifiers/rsa'
import { Resolver } from 'iso-signatures/verifiers/resolver'

const message = new TextEncoder().encode('hello world')
const resolver = new Resolver(

)
const signer = await EdDSASigner.generate()
const signature = await signer.sign(message)
const verified = await resolver.verify({
  signature,
  message,
  ...signer.did, // Signer and DID both have `alg` property that the resolver uses to find the correct verifier
})
