SecureGmail encrypts and decrypts emails you send in Gmail. This happens all on your machine, and the unencrypted text never reaches Google servers. This is useful if you don't want anyone but the intended recipient to ever read your email (i.e. companies, governments, etc.)

** How To Use **

1) Install the extension
2) Refresh Gmail
3) Click on the lock icon next to the compose button
4) Compose your email and send
5) Enter a password, your recipient will need to enter the same password.


** Open source**

With any security project, community involvement is the key to helping identify flaws and verify the what the app is actually doing. We've posted the entire project on github: https://github.com/StreakYC/StreakSecureGmail. We'd love to make this better so pull requests are always welcome!


** How secure is it? **

SecureGmail uses symmetric encryption to encrypt and decrypt each message. The password is decided by the user and assumes the recipient already knows it. SecureGmail is only as good as your password, pick an easy to guess password and it will be easy to break. Shared knowledge can be a useful and convenient password. Remember to never email or IM your password for others to intercept.

SecureGmail uses an open source JS crypto library from Stanford available here (http://crypto.stanford.edu/sjcl/) and also on Github (http://github.com/bitwiseshiftleft/sjcl).

** Works With Google Apps **

SecureGmail is compatible with any of your Gmail accounts and you can use them across accounts simultaneously. SecureGmail works on personal Gmail accounts or accounts provided by your organization, school, or business.
