📖 Project Explanation

Secureption is a web-based encryption and decryption tool that implements the RSA asymmetric encryption algorithm using Python and Flask. The main goal of this project is to help users understand how public-key cryptography works through a simple and interactive interface.

Unlike traditional symmetric encryption where the same key is used to both encrypt and decrypt data, RSA uses a pair of keys:

• A public key that is shared and used to encrypt messages
• A private key that is kept secret and used to decrypt messages

The application allows users to:

• 🔐 Generate secure RSA key pairs (2048-bit strength)
• 📥 Encrypt plaintext messages using the public key
• 📤 Decrypt encrypted messages using the private key
• 📄 Work with Base64 output, making ciphertext easy to copy and share

Secureption is designed with beginners, students, and security enthusiasts in mind. It provides a practical understanding of:

• How secure message transmission works
• The concept of key management
• The basics of cryptographic padding (OAEP with SHA-256)

The backend uses Python’s cryptography library to ensure secure and proper implementation of encryption standards. The frontend is powered by Flask and provides a simple web interface where users can test encryption without needing to write any code.

Whether you're a cybersecurity student, a developer experimenting with cryptography, or just curious about how encryption protects your data — Secureption is a great tool to learn, test, and explore.
