Symmetric Encryption Example

This would be the example shown where the same key is shared between the communicating parties. Examples are Advanced Encryption Standard (AES), the Data Encryption Standard (DES), and Blowfish Cipher.

In comparison to Asymmetric Encryption, symmetric encryption is usually faster, but it can be difficult to share the key with both parties securely.
