TripleDES-Encryptor-Decryptor

A simple web-based tool for performing Triple DES (3DES) encryption and decryption directly in your browser.

Overview

This project provides an HTML page that allows users to encrypt and decrypt text using the Triple DES algorithm in ECB mode with PKCS7 padding. The tool is built using plain HTML, CSS, and JavaScript, utilizing the CryptoJS library for cryptographic functions.

Features

• Encrypt Text: Input plaintext and a key to generate ciphertext.
• Decrypt Text: Input ciphertext and a key to retrieve the original plaintext.
• Toggle Mode: Seamlessly switch between encryption and decryption modes.
• No External Dependencies: Runs entirely in the browser without the need for server-side code or installations.

Getting Started

Prerequisites

• A modern web browser (Chrome, Firefox, Edge, Safari).

Usage

1. Clone or Download the Repository

   git clone https://github.com/yourusername/TripleDES-Encryptor-Decryptor.git

2. Open the HTML File

   • Navigate to the project directory.
   • Open index.html in your web browser.

3. Encrypting Text

   • Select the Encrypt mode.
   • Enter your Key (encryption key).
   • Enter the Plaintext you wish to encrypt.
   • Click the Encrypt button.
   • The Ciphertext (Base64 encoded) will be displayed.

4. Decrypting Text

   • Select the Decrypt mode.
   • Enter your Key (must be the same as used for encryption).
   • Enter the Ciphertext (Base64 encoded) you wish to decrypt.
   • Click the Decrypt button.
   • The Decrypted Text will be displayed.

Example

• Key: Test_Key
• Plaintext: Hello World
• Ciphertext: p9vn6X7NFoLHeGIfusyALQ==

Security Considerations

Important: This tool is intended for educational purposes to demonstrate how Triple DES encryption and decryption work. Triple DES and ECB mode are considered outdated and insecure for protecting sensitive data. They are vulnerable to various cryptographic attacks and should not be used for securing confidential or personal information.

• Triple DES (3DES): Deprecated by NIST since 2017 due to its smaller block size and susceptibility to cryptographic attacks.
• ECB Mode: Does not use an initialization vector (IV) and can reveal patterns in the plaintext.

Recommendation: For modern encryption needs, consider using AES (Advanced Encryption Standard) with secure cipher modes like CBC (Cipher Block Chaining) or GCM (Galois/Counter Mode).

Dependencies

• CryptoJS Library: Included via CDN in the HTML file.
