 * # Webcrypto Key Did Provider
 * This is a DID Provider which implements [EIP2844](https://eips.ethereum.org/EIPS/eip-2844) for `did:key:` using webcrypto with non-extractable keys.
 *
 * ## Installation
 *
 * ```
 * npm install --save @didtools/key-webcrypto
 * ```
 *
 * ## Usage
 *
 * ```js
 * import { CryptoKeyProvider, generateP256KeyPair } from '@didtools/key-webcrypto'
 * import KeyResolver from 'key-did-resolver'
 * import { DID } from 'dids'
 *
 * const keyPair = generateP256KeyPair()
 * const provider = new WebcryptoProvider(keypair)
 * const did = new DID({ provider, resolver: KeyResolver.getResolver() })
 * await did.authenticate()
 *
 * // log the DID
 * console.log(did.id)
 *
 * // create JWS
 * const { jws, linkedBlock } = await did.createDagJWS({ hello: 'world' })
 *
 * // verify JWS
 * await did.verifyJWS(jws)
 * ```
