Usage
const { KeyManager, deriveSeedFrom } = require('@holo-host/wasm-key-manager')
const crypto = require('crypto')
const seed = crypto.randomBytes(32)
const hha_id = new Uint8Array([
66, 123, 133, 136, 133, 6, 247, 116, 4, 59, 43, 206, 131, 168, 123, 44, 54, 52, 3, 53, 134, 75,
137, 43, 63, 26, 216, 191, 67, 117, 38, 142,
])
// or derive seed
const seed = deriveSeedFrom(hha_id, '[email protected]', 'Passw0rd!')
const message = 'Hello World'
const keys = new KeyManager(seed)
const signature = keys.sign(message)
const verified = keys.verify(message, signature)
const public_key = keys.publicKey()
const verified = KeyManager.verifyWithPublicKey(message, signature, public_key)Bundle for web
