Millions of us send billions of emails back and forth each day without much concern for their security. On the whole, security is not a primary concern for most day-to-day emails, but some emails do contain personal, proprietary and sensitive information, documents, media, photos, videos and sound files. Unfortunately, the open nature of email means that they can be intercepted and if not encrypted easily read by malicious third parties. Even with the PGP - pretty good privacy - encryption scheme first used in 1995, if a sender's private "key" is compromised all their previous emails encrypted with that key can be exposed.
