AES + RSA Hybrid Encryption Demonstration
Present By Vivek Boricha
01 · Enter Message
The sender enters a plaintext message and encrypts it using AES-256-GCM.

How Hybrid Encryption Works
1. AES EncryptionA random AES-256 key encrypts the message with AES-GCM.
2. RSA ProtectionThe recipient's RSA public key encrypts the AES key.
3. Manual TransmissionSender copies the ciphertext and protected AES key to the recipient.
4. DecryptionRecipient pastes both values, RSA recovers the AES key, then AES decrypts the message.
