Hybrid Encryption

Giriş
Açıklaması şöyle. Veri simetrik şifreleme ile şifrelenir. Bu yöntem hızlıdır. Daha sonra anahtar asimetrik şifreleme ile şifrelenir. Bu da hızlıdır çünhü anahtar çok büyük değildir.

Hybrid encryption as the name suggests combines the best of both the worlds of symmetric and asymmetric encryption and allows us to encrypt the data efficiently while ensuring secrecy is not compromised .

At the client end, we encrypt the data with symmetric encryption using secret key. The secret key is then encrypted with the asymmetric public key. Then, both the encrypted key and encrypted data are sent to the receiver.

At the receiver end the secret key is retrieved by decrypting the encrypted secret key with the private key. The secret key is then used to decrypt the encrypted data.

But the time to encrypt the data with asymmetric encryption grows significantly proportionately with the size of data. Here symmetric encryption does the job quite efficiently.
