Isomorphic encrypted key store. Works in node and in the browser.
🔒 Strong encryption to securily store sensible data
🔑 Supports distinct passwords for each key
🔍 Can store unencrypted data alongside each key
Attention: The data is stored in a truly secure way. If you lose your password you will not be able to recover the wallet data! So please make sure to store a backup of the private data in a safe place.
$ npm install --save key-storeUsing yarn:
$ yarn add key-storeimport { createStore } from 'key-store'
const store = createStore(saveFile, initialData)
await store.saveKey('test-key', 'arbitrary password', { privateKey: 'super secret private key' })
const { privateKey } = store.getPrivateKeyData('test-key', 'arbitrary password')
console.log(`Stored private key: ${privateKey}`)
console.log(`All stored keys' IDs: ${store.getKeyIDs().join(', ')}`)Writing and reading keys to a file in node is easy:
import * as fs from 'fs'
import * as util from 'util'
import { createStore } from 'key-store'
const readFile = util.promisify(fs.readFile)
const writeFile = util.promisify(fs.writeFile)
async function createFileStore (filePath) {
const saveKeys = data => writeFile(filePath, JSON.stringify(data), 'utf8')
const readKeys = async () => JSON.parse(await readFile(filePath, 'utf8'))
return createStore(saveKeys, await readKeys())
}All data private data is encrypted using tweetnacl's xsalsa20-poly1305 implementation. The encryption key is derived from the password using PBKDF2/SHA256. The iteration count for the PBKDF2 invocation is configurable and defaults to 10,000 rounds.
