## Files
- src: the file that implements de solution.
## Features
The main features of the application include:
- Message Encryption: The program allows users to encrypt messages by providing three prime numbers (p, q, and e) as input. It performs the encryption using the RSA algorithm and generates an encrypted message.
- Message Decryption: Users can decrypt encrypted messages by providing the same prime numbers (p, q, and e) used for encryption. The program uses modular arithmetic to decrypt the message and displays the original decrypted text.
- User Interaction: The program presents a menu-based interface that allows users to choose between encryption and decryption options. It prompts users for input, such as prime numbers and messages, to perform the desired operation.
- Secure Encryption Algorithm: The script utilizes the RSA encryption algorithm, which is a widely-used public-key encryption method known for its security. It ensures that the encrypted messages can only be decrypted using the corresponding private key.
- Input Validation: The program validates user input to ensure that the provided prime numbers are correct and appropriate for encryption and decryption operations.
