As far as I know Email is unencrypted and cannot be encrypted. However, you may be able to throw the information/data into an encrypted file and attach it to an email then encrypt it once it gets back into your computer.

I’m not positive on the email encryption thing so if anyone else knows for sure let me know.

You can use PGP to encrypt the email. Conversely, you could use some hashing or encryption algorithm like MD5 to scramble the field. Once you receive the email, you can decode it yourself.

SSL is involved in the sense that you can accept a client-side certificate. That will bring you a public RSA key.

With that key you can create a propperly formatted, secure (in the sense that only who posseses the private part of that key will be able to read the contents) email. That email is not secure in itself (it can travel through many servers and each get a chance to read it), but the contents are (what those servers will read will not make sense).
