memcached-encrypted-store

A secure and efficient encrypted store of keys and values for memcached.

Welcome to memcached-encrypted-store! This NPM package provides a convenient solution for storing encrypted data in memcached, ensuring the confidentiality and integrity of your cached information. With memcached-encrypted-store, you can protect your sensitive data while benefiting from the speed and scalability of memcached.

Features

• Securely store and retrieve keys and values in memcached
• Encryption of data with non-persistent symmetrical keys
• Data integrity verification to prevent tampering
• Configurable cache settings for optimal performance
• Simple and intuitive usage

Installation

To start using memcached-encrypted-store in your project, simply install it via npm:

npm install @exact-realty/memcached-encrypted-store

Usage

To use memcached-encrypted-store, follow these steps:

1. Import the necessary modules:

import m from '@exact-realty/memcached-encrypted-store';
import Memcached from 'memcached';

1. Initialize the encrypted memcached instance by providing the required configurations:

const encryptedMemcached = await m({
  cacheMinAge: 1,
  cacheMaxAge: 60,
  cacheDefaultAge: 30,
  cacheClockDriftAdjustment: 1,
  memcached: new Memcached('memcached-server');
});

1. Store a value in memcached:

const optionalTtl = 5;
await c('some-key', new Uint8Array([1,2,3]), optionalTtl);
// or altenatively (using the default TTL)
await c('some-key', new Uint8Array([1,2,3]));
// or (using object notation)
// note that fetching immediately after will likely fail, as this is
// an asynchronous operation
c['some-key'] = new Uint8Array([1,2,3]);

1. Retrieve a value from memcached:

// Warning: may throw
console.log(await c['some-key']);

1. Delete a value from memcached:

delete c['some-key'];
