Encrypt and decrypt JSON objects easily and safely
npm install json-cryptoEasy to use abstraction on top of Node's native crypto module to safely encrypt and decrypt JSON objects.
``
npm install json-crypto
`js
const { createKey, createCodec } = require('json-crypto');
// Create a random encryption key
const key = createKey();
// Create our codec with { encrypt, decrypt }
const codec = createCodec(key);
// Encrypt a JSON object and return the ciphertext
const ciphertext = codec.encrypt({ message: 'my secret message' })
// Decrypt the ciphertext back into a JSON object
const secret = codec.decrypt(ciphertext)
// secret === { message: 'my secret message' }
`
NB: You'll probably want to persist the generated key and store it somewhere safe.
- Safe by nature (only uses native crypto` functions)
- Safer by forcing you to use unique nonces (see why it matters)
- Easy to use interface for JSON objects
- Ciphertexts are valid URL query argument strings (using encodeURIComponent)
