Criptext lets you recall your Gmail messages and attachments any time

Available for Gmail as an extension for Chrome and Safari, Criptext encrypts your outgoing mail and shows you when it was opened. It converts your email text into an image only when it’s opened, so it can’t be scanned by bots. You can recall a message at any time or set it to self-destruct after a specified time. Criptext also lets you securely send attachments up to 100MB in size. It encrypts your attached files, displays them in a custom attachment viewer and gives you the option to lock them with a password or block printing and downloading.
