One of the most private things that you will do on the internet is to send emails to someone. When we sign up for an email service, we expect them to give us a security standard that is higher than anything else we do on the internet besides banking. Our email accounts are filled with both personal and business secrets that we would like to keep to ourselves. So if anyone was able to get into our emails, it could possibly be a devastating experience for both us and whoever we were sending the email to. But breaking into your account is not the only way that someone would be able to read your private emails. They could also see them as you send them through the network. Lucky for us there are ways that we can stop this from happening. There are several ways that you can encrypt your email messages to keep them quiet as they go through the air. We will discuss these methods and how you can use them when you send your own emails, especially over a wireless network. 
 
Most people who have used the internet, have kind of an ideal of what encryption means. You get an example of it every time that you go to a web site and see that little lock in your browser. When you see that lock, you know that there is a good chance that no one will be able to see your message as you see it. The lock helps you feel safe when you are making a transaction on your bank account.  The act of encryption allows your data to move back and forth, in what seems to the naked eye, as a bunch of scrambled data. It is then translated by software that has the encryption key into readable text. Now the person on the other end can understand what was sent to them. This type of security is exactly what you need when you send an email message out. 
 
There are several programs out there that will encrypt your email messages for you. One of the pieces of software that will do it is called GnuPG. It is free, open sourced software and it is very powerful. It gives you a public and private key that is used to be able to encrypt and decrypt a message. The person who has the private key is able to decrypt the message so that they can read it. If you do not have the private key, even if you are the one who originally sent the email, then you cannot see the message that was sent. There is also a setting that will encrypt messages using Microsoft Outlook. If you are in a hurry, this is a more than reasonable tool to use. 
 
Your email is a private thing; make sure that you keep it that way by using encryption on your messages.
