It isn't just them. At any hop in between you and the destination, the email can be read. > You mention that you post your keys for everyone to use. Where, how do we > get them? How do we use?

You probably already have it, if you use Apple's mail on a Mac. All my mail has a digital signature with my public key. At the top of the window there is a list of headers — including the Security header. (You might have to click Details.) This shows whether the message is securely signed. When it sees a correctly signed message, it puts the public key into your keychain. On iOS, you have to go into the advanced settings for an email account to turn it on. > For those we email frequently and we wish to encrypt do we initiate this by > getting our key and then tell them to also get a key or do we get both sides > of the key and somehow get their key to them? In order for a person to receive encrypted mail, she must get a key pair and send you the public key. If you want two-way encryption, both of you must get key pairs and exchange public keys. > I guess the logistics of how this is done would help as I would pass these > out to those I normally email. The easiest place to get free public keys is Comodo. There are many others — Google knows about them. Look for free email certificates or free S/MIME certificates. (You don’t want SSL certificates.) > Finally, as long as I use Mail does it matter if I am using my Aye.net > account, my TimeWarner account or my Apple account? The key would be through > Apple's Mail and not through the email portals I am assuming? The certificates are keyed to your email address. You need a certificate for each different email address you use. I have four different certificates — one for each of the four addresses I use the most.
