 **Symmetric encryption** is a method of securing data where the **same
 password** is used to both encrypt and decrypt information.

 symmetric encryption relies on a single shared secret (the password). This
 approach is:

 1. You choose a **strong password**.
 2. That password is used to **encrypt** the data.
 3. Anyone with the **same password** can **decrypt** it.
