If you don't have an OpenPGP capable mail user agent, you may encrypt a message to my key using tencrypt that runs in your browser, if you trust it enough. You'd have to copy the result and paste it into your mail's body (or wherever).

GnuPG (The GNU Privacy Guard)
GnuPG is a complete and free replacement for PGP. Because it does not use the patented IDEA algorithm, it can be used without any restrictions. GnuPG is a RFC2440 (OpenPGP) compliant application.

Evil 32: Check Your GPG Fingerprints
Stop using 32bit key ids. It takes 4 seconds to generate a colliding 32bit key id on a GPU (using scallion). Key servers do little verification of uploaded keys and allow keys with colliding 32bit ids. Further, GPG uses 32bit key ids throughout its interface and does not warn you when an operation might apply to multiple keys.

GnuPG Anleitung - Raven Wiki
Die GnuPG Anleitung schlechthin. Geht auch ausfuehrlich auf grafische shells / GUIs ein. Kai Raven meinte in seinem Vorwort zur GnuPG Anleitung sehr richtig:
Mit der Version 3.2 der Deutschen GnuPG Anleitung, die nun schon seit vier Jahren erscheint und der Veröffentlichung von GnuPG 1.4.1 wird gleichzeitig die weitere Pflege der Deutschen PGP Anleitung eingestellt.
Ich denke, GnuPG hat mittlerweile einen ausreichenden Reifeprozess durchgemacht, so breite Verwendung gefunden und durch die Integration in zahlreiche E-Mail und Instant Messaging Programme, genauso wie durch die grafischen Benutzeroberflächen so viel an Benutzerfreundlichkeit gewonnen, dass es für keinen Nutzer des Internets mehr nötig ist, PGP einzusetzen.

The Free Software companies Intevation, g10 Code and Klarälvdalens Datakonsult AB are contracted by the German 'Bundesamt für Sicherheit in der Informationstechnik (BSI)' to incorporate the Sphinx protocols into Free Software MUAs. Background is to ensure availability of alternatives to proprietary desktops.

Public service for the distribution and discovery of OpenPGP-compatible keys, commonly referred to as a "keyserver".
A keyserver service that verifies email addresses before publishing keys. It also does not publish 3rd-party signatures, which if abused can confuse your software, alas with the side effect that without those signatures there's also no web of trust. Trusting signature policies is up to you.
Also as .onion

Do NOT use the MIT PGP Key Server (pgp.mit.edu)
This server uses old software and is a bit dumb, it doesn't understand multiple subkeys or subkeys with multiple signatures and treats them as errors, throwing away the elements and effectively crippling keys. I strongly recommend you use a different server.

The Keysigning Party HOWTO
Introduction to keysigning parties by V. Alex Brennen.
Efficient Group Key Signing Method (archive.org)
Speedup of fingerprint verification step in large keysigning parties.
Keysigning Party Methods - The 'Ad Hoc' Method (archive.org)
The 'Ad-Hoc' method (which is basically a fancy shmancy way of saying "the standard way keysignings have always been done!") is best suited to small groups since it can quickly become chaotic with large numbers of people and does not scale well. However, it requires little or no planning so is very easy with small groups.
Keysigning Party Methods - The 'Sassaman-Efficient' Method (archive.org)
The 'Sassaman-Efficient' method is based on a proposal by Len Sassaman to efficiently manage large keysigning events. It is well suited to large groups. There is also a modified version known as the 'Sassaman-Projected' method.
Keysigning Party Methods - The 'Sassaman-Projected' Method (archive.org)
The 'Sassaman-Projected' method is a modified version of the 'Sassaman-Efficient' method and is well suited to large groups.
The principle difference is that instead of having a folded back line of participants when it comes time to check IDs, a document projector is used to display the ID of each person in turn so that every other participant can clearly see it at the same time. Each participant's ID is therefore examined by everyone else present simultaneously, instead of by each in turn, and the event duration scales linearly with number of participants.

In Debian the tools are part of the signing-party package.
In Fedora it is the pgp-tools package
Pius (PGP Individual UID Signer) helps attendees of PGP keysigning parties. Similar but different to caff. Of course also available in Debian and Fedora.

PGP: Graphing The Trust
sig2dot GPG/PGP Keyring Graph Generator (archive.org)
sig2dot.pl can be used to generate a graph of all of the signature relationships in a GPG/PGP keyring, like those resulting from keysigning parties, or the Debian Keyring (of all Debian developers). It converts the output of "gpg --list-sigs" to a .dot file, which is a graph definition that can be rendered by springgraph or graphviz.
sims | freshmeat.net
sims (sims is more than sig2dot) parses the output of "gpg --list-sigs" and produces graphs of all the signature relationships in different output formats. It aims to be a replacement for sig2dot which provides many new features. Additionally, parsing of the input is much improved.
GPG/PGP Signature Path Tracing (archive.org)

my GnuPG and Enigmail Tips
Tips on installing GnuPG and Enigmail. My attempt to explain that to a Windows user, not running Windows myself..
Enigmail / Forum / Enigmail Support:Upgraded gpg and now gpg fails under enigmail but works at the command prompt
The cause why GnuPG 2.0.23 exits with return code 2 is gpg: Note: signatures using the MD5 algorithm are rejected because there are old keys with MD5 hashes that if --allow-weak-digest-algos is not given lead to a fingerprint of 0x00000000000000000000000000000000 (even if the short/long ID says different) and ultimately to gpg: Oops: keyid_from_fingerprint: no pubkey.
In short: for a workaround delete those old MD5 crap keys from your keyring unless you are forced to use them..
gpg2 --list-key 0x00000000000000000000000000000000
gpg2 --export 0x00000000000000000000000000000000 >md5_keys.gpg
gpg2 --delete-keys 0x00000000000000000000000000000000
(repeat until no such key left)
Note: This is supposed to be fixed in GnuPG 2.0.29, see ⚓ T2000 PGP-2 Keys are handled as if their Fingerprint is always zero
