Create A GPG Key
GnuPG is a complete and free replacement for PGP.
Then enter a 1 to create a standard DSA/ElGamal key. Press Enter.
Type in 2048. Press Enter.
Type in 0. Press Enter.
Enter a y. Press Enter.
Type in your Real Name. Press Enter.
Type in your REAL email address. Press Enter.
Type in your First Name, add a comment if you want. Press Enter.
Type O. Press Enter. It will now create your Key.
You will have to give it a Pass Phrase
- Usually a short sentence or phrase that isn't birthdays, names, etc. of people in your family. I will say this to you, because when it comes to pass phrases, they're not easy sometimes... so write it down. Because what you DON'T want to do is forget it!!
Export Your Key
gpg --export -a "User Name" > public.key
Note that the "User Name" is actually your real full name, not the user name you usually use in Ubuntu, and that the quotes should stay in place around your name.
Submit Your Key
gpg --send-keys --keyserver keyserver.ubuntu.com <KEYID>
Using a webbrowser:
Copy the content of public.key:
Open http://pgp.mit.edu in a browser window.
Paste the copied content in the box under the label, Submit a key
Click on Submit this key to the keyserver!
Get Your Key Signed
Locate someone that lives near you and can meet with you to verify your id. I've used http://www.biglumber.com/
- Arrange for a meeting. Bring at least one ID with photo and printed fingerprint of your key, ask the same from the person you will be meeting with.
- Meet, verify your IDs and exchange fingerprints
- Sign the key of the person you've just met. Send him/her the key you've just signed.
- Update your keys on the keyserver, the signature you've just created will be uploaded.
Use Your Key in Evolution
Go back to http://pgp.mit.edu and type in your name in the Search String box.
- Highlight and Copy the section of the result page under "User ID" (It should be your name, comment, and email address.)
Open Evolution and go to Edit->Preferences.
Choose your email account, click on it, and then click Edit.
Click on the security tab.
In the PGP/GPG Key ID: box, paste the User ID from the web page result.
Click OK. Click Close.
If you want to use your key in any new email, simply click on the Security menu item in your new mail message, and then click on PGP Sign ...
Use Your Key in Mozilla Thunderbird
Install the Enigmail plugin either by:
sudo apt-get install mozilla-thunderbird-enigmail
or by downloading the plugin from [http://enigmail.mozdev.org/ here] and install it manually
Configure GPG in Thunderbird under: Enigmail->Preferences and add under GnuPG executable path the following path /usr/bin/gpg
GUI For GPG Key Management
You can install [http://seahorse.sourceforge.net/ Seahorse] to manage your keys via apt:
sudo apt-get install seahorse
Or search Synaptic for seahorse. Note that you can actually do the entire key creation & exporting process in Seahorse, with a wizard to guide you through the creation if you want.
