In Chapter 6, we looked at symmetric encryption, which is a two-way encryption process that uses the same key for both encryption and decryption of your message, as shown in Figure 7-1.

That data is decrypted using the same key to uncover the original data, or plaintext. This process is referred to as symmetric encryption because we use the same key for both encryption and decryption.
