keycipher is a utility package for encrypting and decrypting text using AES-GCM with a secret key. It leverages the WebCrypto API to provide secure encryption and decryption functionalities.
To install the package, run the following command:
npm install keycipherHere’s a brief guide on how to use the keycipher package.
const { encryptData, decryptData } = require('keycipher');To encrypt a piece of text, use the encryptData function. You need to provide the plaintext and a key string.
const { encryptData } = require('keycipher');
(async () => {
try {
const keyString = 'your-secret-key'; // Replace with your key
const plainText = 'This is a secret message'; // Replace with your text
const encryptedData = await encryptData(plainText, keyString);
console.log('Encrypted Data:', encryptedData);
} catch (error) {
console.error('Encryption Error:', error);
}
})();To decrypt data, use the decryptData function. You need to provide the encrypted data and the same key string used for encryption.
const { decryptData } = require('keycipher');
(async () => {
try {
const keyString = 'your-secret-key'; // Replace with your key
const encryptedData = {
iv: '...your IV...',
cipherText: '...your cipherText...',
tag: '...your tag...'
}; // Replace with your generated encryption object
const decryptedText = await decryptData(encryptedData, keyString);
console.log('Decrypted Text:', decryptedText);
} catch (error) {
console.error('Decryption Error:', error);
}
})();Encrypts the given plaintext using the provided key string.
