- <title>What is Encryption?</title>
- <para>
- Encryption is an ancient method of changing readable text to unreadable
- text that dates back to Egyptian times. 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.

- <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:

- 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.
