Isomorphic AES cipher

Simplified isomorphic API for AES cipher by CryptoJS.

This implementation uses a random salt for every encrypted value and CFB padding. This means if you even encrypt two times the same value with the same password the encrypted result will be both times different. So encrypted values by this method are strong against rainbow tables and all other precomputed tables.

  • 😎 No external dependencies;
  • ㊗️ Has Unicode, Cyrillic, emoji support for values and keys;
  • 👷‍♂️ 100% tests coverage.

Installation

meteor add ostrio:aes-crypto

ES6 Import

1import { AESencrypt, AESdecrypt } from 'meteor/ostrio:aes-crypto';

API

Encrypt

  • AESencrypt(value, password)
    • value {String}
    • password {String}
1AESencrypt('My Plain String', 'TXkgUGxhaW4gU3RyaW5n');
2// Returns: '{"ct":"ZQAp/MEV0pMDn6V7oY5YFVvEGNxvG2eJliNPZpT9U2I=","iv":"0e472d2cd20892ac9cfcf91dea4fe98e","s":"35e808ccc71b8c13"}'

Decrypt

  • AESdecrypt(value, password)
    • value {String} - In form of JSONableString
    • password {String}
1AESdecrypt('{"ct":"ZQAp/MEV0pMDn6V7oY5YFVvEGNxvG2eJliNPZpT9U2I=","iv":"0e472d2cd20892ac9cfcf91dea4fe98e","s":"35e808ccc71b8c13"}', 'TXkgUGxhaW4gU3RyaW5n');
2// Returns: 'My Plain String'

Validate encrypted JSONable String

To validate returned object from AESencrypt function use this regular expression:

1/^{"ct":"([A-Za-z0-9+\/]+(\={0,2}))","iv":"([0-9a-f]{32})","s"\:"([0-9a-f]{16})"}$/;

Example:

1const JSONableString = AESencrypt('My Plain String', 'TXkgUGxhaW4gU3RyaW5n');
2/^{"ct":"([A-Za-z0-9+\/]+(\={0,2}))","iv":"([0-9a-f]{32})","s"\:"([0-9a-f]{16})"}$/.test(JSONableString);
3// Returns: true
4
5AESdecrypt(JSONableString, 'TXkgUGxhaW4gU3RyaW5n');
6// Returns: 'My Plain String'
