Encryption takes the statement + "Evolution" and turns it into something which cannot be read without help + through decryption. + <example> + <title>Encryption Example</title> + <para> + Kevin orders an <application>Evolution</application> t-shirt from + Ximian, Inc. over the internet. He puts in his credit card number + which is 1234-567-8901. For security, his computer encrypts the + credit card number so it can be safely transmitted over the internet. + The number now is @#$23ui7yr87#@!48970fsd, which holds no intentional + resemblance to the inital number. When the information gets to + Ximian, Inc. it'll be decrypted into the inital number. + </para> + </example> + Encryption can be used in email in two ways: to verify that the sender is + the real sender, and to hide the message while in transmission. + <application>Evolution</application> has the capability to do both. + </para> + </sect1> + <sect1 id="generating-key"> + <title>Generating your PGP key</title> + <para> + First, you need to create a PGP key. To do this, you'll need GPG + installed. + </para> + <tip> + <title>GPG Versions</title> + <para> + This manual covers version 1.0.6 of GPG. If your version is different, + this may not be entirely accurate. You may find out your version number + by typing in: <command>gpg --version</command>. + </para> + </tip> + <para> + You can start by typing in: <command>gpg --gen-key</command>. At the + first question, select 1. The next question asks you about key length. + The longer the key, more stronger it is. However, the longer the key, the + longer it takes to generate. This is your choice. However, 1024 bits + (default) should be adequate. The next question asks you if you want your + key to expire. Expiring keys make your key invalid after a certain amount + of time, so old keys don't float around active. This is the same concept + as a coupon at a supermarket. Next, you'll type in your Real name, your + email address, and a comment. You should not forge this information, as + it is used later to verify who you are. Assuming that all your + information is correct, press "O" to continue. GPG now asks you for a + passphrase. This is a password which you will need to decrypt and encrypt + messages. This can be any length, with any characters in it. It is case + sensitive, which means that it does know the difference between capital + letters and lower-case. Now your key is generated. It is recommend you + surf the internet, read your email, or write a letter in a word + processor. This help creates randomness in the key. + </para> + <para> + Once this is completed, you'll be dropped back to the command line. + Now you can view your key information by typing <command>gpg + --list-keys</command>. You should see something similar to this: + <example id="gpg-list-keys"> + <title>GPG Listing Keys</title> + <para> + /home/bob/.gnupg/pubring.gpg + ---------------------------- + pub 1024D/32j38dk2 2001-06-20 bob <bob@bob.com> + sub 1024g/289sklj3 2001-06-20 [expires: 2002-11-14] + </para> + </example> + You'll now need to upload your public key to a keyserver, so that your + friends can use your key.
