What is Message Secure Send?
Message Secure Send (MSS) is a Chrome extension that enables secure and encrypted email exchanges on Gmail™. It simplifies the process of encrypting personal information, such as credit card numbers or social security numbers. Recipients can decrypt the emails by answering a question known only to them. MSS also supports password-based encryption for pre-agreed passwords. Please note that MSS does not encrypt attachments or the subject of the email, and it requires both the sender and recipient to have MSS installed and use Gmail™ on Chrome™.

Extension summary

Message Secure Send (MSS) allows any Gmail™ / Chrome™ users to exchange secure, encrypted emails in just a few clicks. It is perfect for when you'd like to send a credit card number, social security number or other personal information.

Using MSS is simple: when composing an email click the extension, and provide a question your recipient (but not others) will know the answer to. When your recipient gets the email, they answer the question and view your email; other prying eyes will not be able to read it. (Note that your recipient will need to install MSS to read the email - we are working on more support for other browsers and email readers, but Gmail™/ Chrome™ is required today).

MSS also encrypt emails with simple passwords, so you don't have to insert the question into the email if you've agreed upon a password with the recipient in advance.

Limitations of the current version - we are working on these...

  • MSS does not encrypt attachments or the subject of your email
  • MSS, Chrome™ and Gmail™ must be available by your recipient to read the email
