How It Works 🔍

Text Encryption with RSA

RSA (Rivest-Shamir-Adleman) is a public-key cryptographic system that enables secure data transmission. In this project, RSA is used for encrypting and decrypting text messages.

1. Key Generation: The user generates a pair of keys: a public key for encryption and a private key for decryption.
2. Encryption: The plaintext message is transformed into ciphertext using the public key.
3. Decryption: The ciphertext is converted back to plaintext using the private key.

Image Encryption with AES

AES (Advanced Encryption Standard) is a symmetric encryption algorithm widely used for securing data.

1. Key Generation: A secret key is generated for both encryption and decryption.
2. Encryption: The image file is processed to create an encrypted version.
3. Decryption: The encrypted image can be reverted to its original form using the same key.
