Safe E-Mailing for Dummies: This seems very promising. A couple of times I poked around into encrypted email, but I always came away thinking it was a total pain. It’d be nice to see something like this take hold.
When two people using the Ciphire client exchange e-mails, the client intercepts e-mail right after the Send button is pressed, and before it leaves the computer. The recipient’s security certificate is retrieved at the Ciphire Certificate Directory, security checks are performed, and then the message and any attachments are encrypted with the recipient’s key.
Incoming e-mail is also intercepted before it appears in a user’s inbox, the message is decrypted (if necessary) and the sender is authenticated using the corresponding certificate from the Ciphire Certificate Directory.
