| - | ==== 2. The Key Management of Enigmail==== | + | |
| - | + | ||
| - | Once you have Enigmail and GnuPG on your system, you need to populate it with keys: it's pretty useless without them. You need to have your own key pair in order to sign messages and allow anybody to send encrypted messages to you. Furthermore, you will need the public key of a person in order to send that person an encrypted message, or to verify the signature in a message sent by that person. | + | |
| - | \\ Note: Enigmail using gpg tool of gpg2.exe program to encrypt or decrypt message, you can find it from ".\Program Files\GNU\GnuPG\pub\ ". | + | |

| + | It can be divided into two kinds of secure email according to the mail security level. | ||
| - | ==== 3.Combine SmartCard with Enigmailto come into secure e-mail.==== | + | 1. Combine Enigmail with GnuPG to send encrypted messages and sign messages. \\ |
| + | 2. Combine SmartCard and Enigmail to send encrypted messages and sign messages. Encrypting message does not require smart card, but decrypting message must use smart card. Email content and session key are transmitted after encrypted. Thus even if attackers intercept the information, they cannot understand the message or decrypt the message. This makes the mail much securer. | ||
| - | Generally, support for OpenPGP encryption and signing message is provided by Enigmail, and in here, You can using OpenPGP encryption and signing message with SmartCard. | ||
