cdcrypt v1.0.1

cdrypt

This package encrpts and decrypts data(string format)

Installation

npm install cdcrypt

How it works

It uses the crypto module built into Node.js to perform AES-256-CBC encryption and decryption. It has two functions: encrypt and decrypt

The encrypt function takes a string as input and returns an object with two properties: iv, which is the initialization vector used in the encryption process, and encryptedData, which is the encrypted data as a hex string

The decrypt function takes the encrypted object as input and returns the decrypted string. It first converts the iv and encryptedData properties from hex strings to buffers, and then uses the crypto.createDecipheriv() method to create a decipher object. The update() method is called with the encrypted text as input, and then the final() method is called to complete the decryption process. The resulting buffer is then converted to a string using the toString() method.

The example usage at the bottom of the code shows how to use the encrypt and decrypt functions. The original text is encrypted and then decrypted, and the original and decrypted texts are logged to the console for verification

Example Usage

const cdcrypt = require("cdcrypt")


let originalText = 'This is a secret message';
let encryptedText = cdcrypt.encrypt(originalText);
let decryptedText = cdcrypt.decrypt(encryptedText);
console.log('Original Text:', originalText);
console.log('Encrypted Text:', encryptedText);
console.log('Decrypted Text:', decryptedText);

Output

Original Text: This is a secret message
Encrypted Text: {
  iv: '84ab48f30e98b91e56fd389a4233b40c',
  encryptedData: 'c98e79f0abee86d7a249cd55dc5b2773b2ee96840c23ffd3a908fce55cef4bcd'
}
Decrypted Text: This is a secret message
