Hello! My name is*****
I am a certified computer professional who will assist you with the problem you described.
In order for the Secure Mail for Gmail by Streak to work, you will need to install Google Chrome web browser since it is a Google Chrome extension. So, if you don't already have Google Chrome installed, you can download it on this link:
After the installation, add the "Secure Mail for Gmail by Streak" extension by clicking on this link:
Once the extension has been installed, access your GMail account with Google Chrome. Next to the standard "Compose" button, you should see the lock icon meaning Secure Mail is ready for use. Click on that lock and you will see the compose window along with the "-Secured" text at the top. Compose your e-mail and click on the "Send Encrypted" button. You will then be asked to enter a password, and password ***** which is optional. Finally, click on the "Encrypt & Send" button and your e-mail will be sent encrypted.
The recipient will see your name (e-mail address) and the subject, but the e-mail contents will be encrypted. It will look like some gibberish. In order for the recipient to decrypt the e-mail, they also need to use Google Chrome with the "Secure Mail for Gmail by Streak" extension installed. If they don't have it installed, a link for the extension will be included.
Once the correct password ***** been entered, gibberish will be replaced with the real content you sent.
I suggest sending some test e-mails to yourself first to see how it works. If you require further assistance, let me know.
