2.2.1 • Public • Published

A simple wrapper over localStorage/sessionStorage using CryptoSubtle

The code is based on MDN https://developer.mozilla.org/en-US/docs/Web/API/SubtleCrypto

How to use

import myCrypto from '@plamikcho/pbCrypto';

const encryptedStorage = getEncryptedStorage(localStorage, 'mysupersecret', 'salt');

encryptedStorage.setItem('test', 'Some text to store encrypted')
  .then(() => encryptedStorage.getItem('test'))
  .then(item => console.log(item));
  .catch(error => console.log(error));

If you don't need the storage, here is it:

const cryptoWrapper = getPbCrypto('secret', 'pepper');
const iv = cryptoWrapper.getIv();
cryptoWrapper.encrypt('ДобАр ден,аз съм вашта леля!', iv)
  .then(encrypted => cryptoWrapper.decrypt(encrypted, iv))
  .then((decrypted) => console.log(decrypted));

Supported browsers at the moment: Firefox and Chrome. MDN says that Edge also should work but it doesn't (at least I was not able to find the proper input params). Any help will be appreciated.
