E-mail is an incredible communications tool, but it isn’t very private. As it travels between sender and recipient across the Internet, malicious entities can intercept and scan it at many points along the way. That anyone would bother to do so for everyday e-mail is highly unlikely, but if you want genuinely private communication, you will need to encrypt your messages. It aint simple but if you want secure email, its the only way to go.
The problem is, e-mail encryption can be a real pain. First you have to create a digital ID, in the form of a certificate from a third party. Then you must exchange IDs with every person to whom you might want to send a protected message. And you’ll need to back up your certificate religiously. Lose it (after a hard-drive crash, for instance), and you’ll lose not only the ability to send or receive new encrypted e-mail, but also any chance of reading previously sent protected e-mail.
But with a little guidance and care, you can send business secrets (or sweet nothings) that only the intended recipient can read.
