ed25519 HD Key
=====

Version 2.0.0
------------

I've rebuilt the library from the ground up for version 2.0.0. It now uses `@noble/ed25519` and `@noble/hashes`. These libraries are faster, audited, and cleaner.

If you need to use `tweetnacl`, you can stick with version 1.3.0.

Usage

**example:**

```js
const { derivePath, getMasterKeyFromSeed, getPublicKey } = require('ed25519-hd-key')
const hexSeed = 'fffcf9f6f3f0edeae7e4e1dedbd8d5d2cfccc9c6c3c0bdbab7b4b1aeaba8a5a29f9c999693908d8a8784817e7b7875726f6c696663605d5a5754514e4b484542';

const { key, chainCode } = getMasterKeyFromSeed(hexSeed);
console.log(key.toString('hex'))
// => 2b4be7f19ee27bbf30c667b642d5f4aa69fd169872f8fc3059c08ebae2eb19e7
console.log(chainCode.toString('hex'));
// => 90046a93de5380a72b5e45010748567d5ea02bbf6522f979e05c0d8d8ca9fffb

const { key, chainCode} = derivePath("m/0'/2147483647'", hexSeed);

console.log(key.toString('hex'))
// => ea4f5bfe8694d8bb74b7b59404632fd5968b774ed545e810de9c32a4fb4192f4
console.log(chainCode.toString('hex'));
// => 138f0b2551bcafeca6ff2aa88ba8ed0ed8de070841f0c4ef0165df8181eaad7f

console.log(getPublicKey(key).toString('hex'))
