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. You'll need to know the ID of your key, which - is after the 1024D on the line beginning with pub. For this example, it - is 32j38dk2. You now type in <command>gpg --send-keys --keyserver - wwwkeys.pgp.net 32j38dk2</command>. Substitute your key ID for 32j38dk2. - You will be prompted to type in your password <!-- verify that you need to - enter your password here --> and your key will be uploaded for your - friends to download. - </para> - </sect1> - <sect1 id="encrypt-evo-integ"> - <title>Setting up Evolution's Encryption</title> - <para> - You'll need to open - <menuchoice> - <guimenu>Tools</guimenu> - <guimenuitem>Mail Settings</guimenuitem> - </menuchoice> - Once there, select the account you'd like to associate the key to and click - the <guibutton>Edit</guibutton> button.
