Encrypt-Text Package

The encrypt-text package is a simple npm package for text encryption and decryption using a basic Caesar cipher algorithm. Please note that this package is intended for educational and demonstration purposes and should not be used for sensitive or secure data encryption.

Installation

You can install the encrypt-text package in your Node.js project using npm:

npm install text-encryption-service-v1

Usage

Once installed, you can use the package by requiring it in your JavaScript code:

const { encrypt, decrypt } = require('encrypt-text');

Encrypting Text

To encrypt a text using a Caesar cipher, use the encrypt function:

const encryptedText = encrypt(text, shift);

• text: The text you want to encrypt (a string).
• shift: The shift value for the Caesar cipher (an integer).

Decrypting Text

To decrypt an encrypted text using the same Caesar cipher, use the decrypt function:

const decryptedText = decrypt(encryptedText, shift);

• encryptedText: The text previously encrypted using the encrypt function.
• shift: The same shift value used for encryption (an integer).

Example

Here's an example of how to use the package:

const { encrypt, decrypt } = require('encrypt-text');

const text = 'Hello, World!';
const shift = 3;

// Encrypt the text
const encryptedText = encrypt(text, shift);
console.log('Encrypted:', encryptedText);

// Decrypt the text
const decryptedText = decrypt(encryptedText, shift);
console.log('Decrypted:', decryptedText);

Error Handling

The package provides basic error handling for invalid input. If you pass incorrect or invalid arguments to the functions, you will receive an error message.

Security Considerations

Please be aware that the Caesar cipher used in this package is not suitable for secure data encryption. It is a simple demonstration of encryption principles. For secure applications, consider using industry-standard encryption libraries and algorithms.
