Go!


I remember reading about this in some magazine way, way back in the day, an article about the guy who invented it mainly. I've just never needed it. Recently I've run into some spots where I might, so time to learn something new.

I know I need a key generator or some kind of software package. What do you recommend? Does it even matter since it really isn't doing anything terribly complex?

Thanks.

GPG is the main open source OpenPGP client:

There's a Windows package that includes the Kleopatra GUI for GPG:

Pfffft, speak for yourself. I had yet to meet someone I know, in person or online that uses GPG or any kind of email encryption/privacy software.

By everyone I think genjix meant "everyone who is using encryption for their personnal messages".


Personnally I don't know any other encryption/signing software.

There's the original PGP. They don't offer any freeware versions that I know of, but the source code is public, so you could compile your own version for free.

If you plan to use it for email, I recommend the Enigmail plugin for Thunderbird.  It uses gpg, which must be installed separately.

GPG comes standard with many (most?) Linux distributions.

Here is a good howto for Ubuntu:

https://help.ubuntu.com/community/GnuPrivacyGuardHowto

It works with email programs like Evolution, KMail and Thunderbird. Of course, it can also be used to encrypt arbitrary data.

You can install it on other platforms besides Linux: Windows (with support for Outlook), OS X (with support for Mail.app), Solaris, etc.

When you become a real linux geek, you'll use mutt and you'll find out how easy it is to use with GPG.

Here are some links for the most common/popular GnuPG packages.

For Windows:
http://www.gpg4win.org/doc/en/gpg4win-compendium.html

For OS X:
http://www.gpgtools.org/

For Ubuntu:
https://help.ubuntu.com/community/GnuPrivacyGuardHowto

For Thunderbird (cross-platform):
http://enigmail.mozdev.org/documentation/quickstart.php.html

GnuPG and Bitcoin are complementary tools. Without GPG, a person cannot truly leverage the power of Bitcoin, secure his/her wallet or establish a strong trust identity.

Glad you are using GnuPG.  Here's my PGP public key, if anyone feels like sending me an encrypted message for fun:

 I use the free hushmail forms and put it in my signature so anyone I email can reply to me privately if they wish.

No one has ever used it.

 GPG works well if you're sitting on a linux box with mutt.

 However, if you're traveling the world logging in from Internet cafes it's a little different. For that the only solution I've found to really work is logging in with a one time password over ssh.
 
 Compare that experience with gmail and it's not great.

It's a shame firegpg is discontinued with gmail.

 I tried setting up my own webmail with squirrelmail to help the process and just something to do. I found that in order to get an SSL cert I had to give my name (`the natural person` - can't use a company), or pay. How a real person can be represented by an SSL cert? I don't want my voice to be used by a machine if possible, because I could be sued for libel if someone says something someone else doesn't like on my wiki.

 Basically because I don't have my own computer with me all the time I find it very hard to use PHP/GPG. Especially with a mobile phone. Then of course you have the problem of the person at the other end not using PGP either.


 ^ all this took a lot of finding out. I generally don't send anything protected or signed anymore until I can find something better.  Hope this helps someone out there though.

Normal.  There is no magic :  you can't use key pair cryptography properly if you don't physically own the machine where your private key is stored.

Hopefully this will change in a few years when Smartcard readers will be on most computers and/or smartphones.

Could you impart some of your knowledge about this to us.  I am very interested.  Are you saying that SSL Certificate Authorities are centralized possible points of control?  How?  Are there decentralized alternatives?

Is it not possible for me to setup my own mail server on my own VPS, such that all my mail could be provably private (without my VPS or anyone else being able to decrypt my messages)?
