How to send and receive an encrypted email

Assuming you've already downloaded the software for your device and followed the easy built-in set up instructions, here is how to send and receive an encrypted email.

We're using a Gmail account but it works the same exact way with any email address.

We're also using Safari on a MacBook Pro, but the process is identical on any browser on Mac or Windows, as well as our iOS, iPad, and Android mobile apps.

1. COMPOSE MESSAGE

From INBOX, click COMPOSE button and the New Message window will open. We are sending this message to our info@securemyemail.com mailbox which is NOT enrolled in SecureMyEmail so you can see what it looks like to send to a recipient that is NOT using SecureMyEmail.

2. CHOOSE EMAIL ENCRYPTION OPTION

When you click the SEND button, you will see two encryption options: (Send Encrypted and Send Encrypted+).

Send Encrypted - just select an expiration date (one hour up to 30 days) and send it. No password, key exchange, software, or registration is required by the recipient(s).

NOTE: You will always retain an encrypted copy of the email in your SENT and ENCRYPTED folders if you ever need to review or resend it.

Send Encrypted+ - If you believe your recipient's email is compromised or hacked (or they are being pursued by aliens or something), this method utilizes symmetrical encryption using the renowned ChaCha20-Poly1305 cipher suite.

On top of the encryption, this option also requires the recipient to know a password to decrypt the email. You will create and enter this password as shown below and then send it to your recipient via text, phone, or just use the optional HINT field so they can deduce it themselves.

NOTE: Although this method is largely overkill, it does ensure absolute zero-knowledge end-to-end encryption. Even if your recipient's email is hacked, the email and attachments are encrypted and inaccessible without the password. Which the hackers won't have so they cannot open it. ;-)

After you choose the password, you will choose when the message will expire (be deleted from our servers forever) and SEND.

3. WHAT THE RECIPIENT SEES WHEN THEY RECEIVE YOUR ENCRYPTED EMAIL

Your recipient will just receive a regular email. We do add "(encrypted)" to the subject to be fancy and help the email stand out a bit more.

When they click "Unlock Message" this will verify they are the owner of the email account, a browser window will open, and we will thank them. They only need to do this once. If you continue the conversation, they do NOT have to verify again.

NOTE: If you sent with a password, they do NOT have to verify their email and they will have immediate access to the email once they enter the password.

If you sent without a password, they will then receive a second email. In this email, we add "(verified)" to the subject to help it stand out.

When they click "View Secure Message" we open an encrypted tunnel from their device to our secure web interface where they read the message. If there are attachments, they can securely download them here too.

They can then reply and we will encrypt the email and send back to you.

4. WHAT YOU SEE WHEN THEY REPLY

The email is highlighted in the SecureMyEmail software with a padlock to show it is encrypted. You can now reply, delete, or save the message. You will also retain a secure copy in your SENT and ENCRYPTED folders.

NOTE: You will see encrypted messages in any email client/webmail that you use, but you will only be able to read and reply to encrypted emails in your SecureMyEmail software or mobile apps.
