What Does an Encrypted Email Mean on Gmail?

Sending an unencrypted email is the same as sending a letter with your message written in clear, easy-to-read text. If someone intercepts your email, the recipient can read what you wrote.

To make sure your private messages stay safe, most email services use something called email encryption. They use a special code to scramble your message into something called ciphertext.

This ciphertext makes it impossible for someone to read your email, even if they somehow get hold of it or access your email server without permission.

Email encryption is like mixing up the words in an email to make it a secret code only you can understand.

The public key infrastructure (PKI) is a system for scrambling and unscrambling emails. Each person gets a special code called a public and private key.

The public key is kept on a special server with the person's name and email; anyone can use it.

The private key is used to unlock these secret emails. It's kept safe and private on your computer, and only you can use it. This key can also confirm that a message came from you.
