This program is optimized and implemented without relying on external libraries, offering a clean and straightforward approach to encryption and decryption.\r\n\r\n---\r\n\r\n## Features\r\n\r\n- **Encrypt messages** using the Vigenère Cipher algorithm.\r\n- **Decrypt messages** to retrieve the original text.\r\n- **Custom key support** for personalized encryption.\r\n- Simple and efficient implementation in Python.\r\n\r\n---\r\n\r\n## Table of Contents\r\n\r\n- [About the Vigenère Cipher](#about-the-vigenère-cipher)\r\n- [Requirements](#requirements)\r\n- [Installation](#installation)\r\n- [Usage](#usage)\r\n- [Examples](#examples)\r\n- [Contributing](#contributing)\r\n- [License](#license)\r\n\r\n---\r\n\r\n## About the Vigenère Cipher\r\n\r\nThe Vigenère Cipher is a polyalphabetic substitution cipher that uses a keyword to encrypt a message. Each letter in the plaintext is shifted by a value determined by the corresponding letter in the key, creating a more secure encryption than simple substitution ciphers.\r\n\r\n---\r\n\r\n## Requirements\r\n\r\n- Python 3.x\r\n\r\nNo additional libraries or dependencies are required.\r\n\r\n---\r\n\r\n## Installation\r\n\r\n1. Clone the repository:\r\n\r\n    ```bash\r\n    git clone https://github.com/Darshan-KC/Python-Vigenere-Cipher.git\r\n    cd Python-Vigenere-Cipher\r\n    ```\r\n\r\n2. Ensure you have Python 3.x installed.\r\n\r\n---\r\n\r\n## Usage\r\n\r\nRun the program using Python:\r\n\r\n```bash\r\npython vigenere_cipher.py\r\n```\r\n\r\nYou can follow the prompts to either encrypt or decrypt a message.\r\n\r\n---\r\n\r\n## Examples\r\n\r\n### Encrypting a Message\r\n\r\nInput:\r\n```\r\nEnter plaintext: HELLO\r\nEnter key: KEY\r\n```\r\nOutput:\r\n```\r\nEncrypted text: RIJVS\r\n```\r\n\r\n### Decrypting a Message\r\n\r\nInput:\r\n```\r\nEnter ciphertext: RIJVS\r\nEnter key: KEY\r\n```\r\nOutput:\r\n```\r\nDecrypted text: HELLO\r\n```\r\n\r\n---\r\n\r\n## Contributing\r\n\r\nContributions are welcome!
