Understanding Encryption in Gmail
Before we dive into the steps, let’s understand what encryption is and how it works in Gmail. Encryption is the process of converting plaintext (readable data) into ciphertext (unreadable data) using a secret key. In Gmail, encryption is used to protect emails from being intercepted or accessed by unauthorized parties.
