-A `did:key` method driver for the [`did-io`](https://github.com/digitalbazaar/did-io)
-client library and for standalone use.
-
-The `did:key` method is used to express public keys in a way that doesn't 
-require a DID Registry of any kind. Its general format is:
-
-```
-did:key:<multibase encoded, multicodec identified, public key>
-```
-
-So, for example, the following DID would be derived from a base-58 encoded 
-ed25519 public key:
-
-```
-did:key:z6MkpTHR8VNsBxYAAWHut2Geadd9jSwuBV8xRoAnwWsdvktH
-```
-
-That DID would correspond to the following DID Document:
-
-### Example DID Document

-
-## Security
-
-The `keyAgreement` key is a Curve25519 public key (suitable for 
-Diffie-Hellman key exchange) that is deterministically _derived_ from the source 
-Ed25519 key, using  [`ed2curve-js`](https://github.com/dchest/ed2curve-js). 
-
-Note that this derived key is optional -- there's currently 
-[no proof](https://crypto.stackexchange.com/questions/3260/using-same-keypair-for-diffie-hellman-and-signing/3311#3311) 
-that this is safe to do.
-
-## Install
-
-Requires Node.js 8.3+
-
-To install locally (for development):
-
-```
-git clone https://github.com/digitalbazaar/did-method-key.git
-cd did-method-key
-npm install
-```
-
-## Usage
-
-To generate a new key and get its corresponding `did:key` method DID Document:
-
-```js
-const didKeyDriver = require('did-method-key').driver();
-
-const didDocument = await didKeyDriver.generate(); // Ed25519 key type by default
-
-JSON.stringify(didDocument, null, 2);
-```
-
-To get a DID Document for an existing `did:key` DID:
-
-```js
-const didDocument = await didKeyDriver.get({did: 'did:key:z6MkpTHR8VNsBxYAAWHut2Geadd9jSwuBV8xRoAnwWsdvktH'});
-```
-
-(Results in the [example DID Doc](#example-did-document) above).
-
-If you have an existing [`crypto-ld`](https://github.com/digitalbazaar/crypto-ld) 
-key pair, you can convert it to a `did:key` method DID Doc:
-
-```js
-const {Ed25519KeyPair} = require('crypto-ld');
-const {keyToDidDoc} = require('did-method-key').driver();
-
-const edKey = await Ed25519KeyPair.generate();
-
-keyToDidDoc(edKey);
-
-// Returns a DID Document
-```
