Symmetric, Asymmetric and Hybrid Encryption

Encryption is the method by which data is converted from a readable form to an encoded version that can only be decoded by another entity if they have access to a decryption key. Encryption is one of the most important methods for providing data security, especially for end-to-end protection of data transmitted across networks.

1. Symmetric encryption:

2. Asymmetric encryption:

Now, Why do you need two keys?

You use one to encrypt your data, which is called public key, and the other to decrypt the encrypted message, which is called the private key.
When you encrypt your message using, let’s say, your granny’s public key, that same message can only be decrypted using her private key.

Private keys:

Public keys

In order to understand what I’ve written above take a look at the image below:

3. Hybrid Encryption:

Hybrid encryption is used in all forms of internet communication between client and server these days.

SSL handshake is one good example of Hybrid encryption.
