The hybrid encryption uses symmetrical and asymmetrical methods in order to encrypt the data. So, it combines the benefits of both methods. In that method, the data are encrypted symmetrical. The keys, however, are delivered with the asymmetrical encryption.
At first, the sender encrypts the data with a random key that has created already. The data can be decrypted by the recipient with the same key (symmetric encryption). Now, the sender should encrypt the key (that has created before) asymmetrically. Then, the key and the data can be sent to the recipient. Finally, the recipient can decrypt the key with his/her private key and with the mutual key he/she can decrypt the data. .
