What SecureStorage Looks Like

$3

`JavaScript
var CryptoJS = require("crypto-js");

var SECRET_KEY = 'my secret key';

var secureStorage = new SecureStorage(localStorage, {
hash: function hash(key) {
key = CryptoJS.SHA256(key, SECRET_KEY);

return key.toString();
},
encrypt: function encrypt(data) {
data = CryptoJS.AES.encrypt(data, SECRET_KEY);

data = data.toString();

return data;
},
decrypt: function decrypt(data) {
data = CryptoJS.AES.decrypt(data, SECRET_KEY);

data = data.toString(CryptoJS.enc.Utf8);

return data;
}
});

var data = {
secret: 'data'
};

// there is no need to stringify/parse you objects before and after storing.

secureStorage.setItem('data', data);
// stores in localStorage like:
// key => value
// "ad36d572..." => "w1svi6n..."

var decryptedData = secureStorage.getItem('data');
// returns { secret: 'data' }

secureStorage.removeItem('data');
// removes the entry 'data'

secureStorage.key(id)
// returns the hashed version of the key you passed into setItem with the given id.

secureStorage.clear();
// clears all data in the underlining sessionStorage/localStorage.

secureStorage.length;
// the number of entries in the underlining sessionStorage/localStorage.
