@aws-crypto/cache-material

What is @aws-crypto/cache-material?

@aws-crypto/cache-material is a package provided by AWS that helps manage cryptographic materials in a cache. This is particularly useful for applications that need to perform cryptographic operations efficiently by reusing cryptographic materials.

What are @aws-crypto/cache-material's main functionalities?

Caching Cryptographic Materials

This feature allows you to cache cryptographic materials using the NodeCachingMaterialsManager. The cache is configured with a maximum age, maximum bytes encrypted, and maximum messages encrypted to ensure efficient and secure reuse of cryptographic materials.

const { NodeCachingMaterialsManager } = require('@aws-crypto/cache-material');
const { KeyringNode } = require('@aws-crypto/client-node');

const keyring = new KeyringNode({
  generatorKeyId: 'arn:aws:kms:us-west-2:123456789012:key/abcd-1234-efgh-5678',
  keyIds: ['arn:aws:kms:us-west-2:123456789012:key/abcd-1234-efgh-5678']
});

const cache = new NodeCachingMaterialsManager({
  backingMaterials: keyring,
  maxAge: 300000, // 5 minutes
  maxBytesEncrypted: 1000000, // 1MB
  maxMessagesEncrypted: 1000
});

Other packages similar to @aws-crypto/cache-material

node-cache

node-cache is a simple and fast Node.js internal caching module. While it is not specifically designed for cryptographic materials, it provides a general-purpose caching mechanism that can be used to store and retrieve any kind of data, including cryptographic materials.

lru-cache

lru-cache is a Node.js module that implements a Least Recently Used (LRU) cache. It is a general-purpose caching library that can be used to manage cryptographic materials by evicting the least recently used items when the cache reaches its limit.

memory-cache

memory-cache is a simple in-memory cache for Node.js. It provides basic caching functionalities and can be used to store cryptographic materials temporarily. However, it lacks the specific features and optimizations for cryptographic materials that @aws-crypto/cache-material offers.
