Encrypt your client storage (available for TS & JS)

• Encrypt your storage using AES symmetric encryption algorithm

• JS and TS

🏠 Homepage

Install

npm i @storage-encryption/storage-encryption

How it works

• The constructor of EncryptedStorage takes two arguments:
  • secret(required): the secret key (a string) that we'll use in the encryption
  • storage(optional): localStorage / sessionStorage. storage is localStorage by default.
• Methods provided by encryptedStorage:
  • encrypt(storage_key: string, data: any): void
  • decrypt(storage_key: string): any
  • remove(storage_key: string): void

Encrypt Local/Session Storage (For Typescript)

import {EncryptStorage} from '@storage-encryption/storage-encryption';

// the constructor takes the secret key as a first parameter and an optional
// second parameter as the storage type
// if none is provided it'll be localStorage by default
const encryptStorage = new EncryptStorage(SECRET_KEY, 'sessionStorage');
/*** for a string ***/
encryptStorage.encrypt('storage_key', 'Hello world');
const stringValue = encryptStorage.decrypt('storage_key');

/*** for an object ***/
encryptStorage.encrypt('storage_key', {'name': 'Hello world'});
const objectValue = encryptStorage.decrypt('storage_key');

/*** for a number ***/
encryptStorage.encrypt('storage_key', 1);
const numberValue = encryptStorage.decrypt('storage_key');

/*** for an array ***/
encryptStorage.encrypt('storage_key', [1, 2, 3]);
const arrayValue = encryptStorage.decrypt('storage_key');

encryptStorage.remove('storage_key'); 

Encrypt Local/Session Storage (For Javascript)

const { EncryptStorage } = require('@storage-encryption/storage-encryption')

const encryptStorage = new EncryptStorage(SECRET_KEY, 'localStorage');
/*** for a string ***/
encryptStorage.encrypt('storage_key', 'Hello world');
const stringValue = encryptStorage.decrypt('storage_key');

/*** for an object ***/
encryptStorage.encrypt('storage_key', {'name': 'Hello world'});
const objectValue = encryptStorage.decrypt('storage_key');

/*** for a number ***/
encryptStorage.encrypt('storage_key', 1);
const numberValue = encryptStorage.decrypt('storage_key');

/*** for an array ***/
encryptStorage.encrypt('storage_key', [1, 2, 3]);
const arrayValue = encryptStorage.decrypt('storage_key');

encryptStorage.remove('storage_key'); 

A BETTER WAY TO DO IT

• Instantiate the encryptStorage object in a shared folder and export it
• So you won't have to instantiate it in each file

import EncryptStorage from '@storage-encryption/storage-encryption';

export const encryptSessionStorage = EncryptStorage(SECRET_KEY, 'sessionStorage');
export const encryptLocalStorage = EncryptStorage(SECRET_KEY);
