Crypto operations for Vega supporting Node.js and Browsers

This module supports both CommonJS and ES Modules:

const { VegaWallet, HARDENED } = require('@vegaprotocol/crypto')

VegaWallet.fromMnemonic('...').then(async wallet => {
  const keys = await wallet.keyPair(HARDENED + 0)

  const msg = Buffer.from('Hello world!')
  const signature = await keys.sign(msg)
})

import { VegaWallet, HARDENED } from '@vegaprotocol/crypto'

const wallet = await VegaWallet.fromMnemonic('...')
const keys = await wallet.keyPair(HARDENED + 0)

const msg = Buffer.from('Hello world!')
const signature = await keys.sign(msg)

Note: All APIs are async. In some cases they will run sync, eg in Node.js where loading WASM is sync, or where crypto routines are sync, but everything is kept async as a lowest common denominator between browser APIs and future hardware wallet support.

Derive a new SLIP-10 VegaWallet from a BIP-0039 mnemonic. Note that the mnemonic is not validated before key derivation.

Derive a seed from a BIP-0039 mnemonic. In combination with VegaWallet.fromSeed this is equivalent to VegaWallet.fromMnemonic. Note that the mnemonic is not validated before key derivation.

Derive a new SLIP-10 VegaWallet from a seed.

Generate a new key pair at index, under the Vega specific subtree.

This contains name and version detailing the version used by the instantiated keyPair. Note if this changes in the future other "builder" methods will be exposed to derive newer versions.

Sign msg with key pair kp for optional chainId.

Verify sig is valid for msg under key pair kp for optional chainId.
