Autocrypt in Enigmail 2.0 deaktivieren
Das Verfahren Autocrypt will den Nutzern den manuellen PGP-Schlüsselaustausch abnehmen und ihn dadurch nutzerfreundlich machen. Der PGP-Schlüssel soll im Header jeder E-Mail mitgesendet werden, damit der Empfänger sofort automatisch verschlüsselt antworten kann, ohne sich um den Schlüsseltausch (und Validierung?) kümmern zu müssen. -==- Für die theoretische Begründung der Sicherheit greift Autocrypt auf das Konzept Opportunistic Security (RFC 7435) zurück. Das bedeutet, das die Verschlüsselung nur noch gegen passive Angreifer schützt soll aber nicht mehr gegen aktive Angreifer, die sich als man-in-the-middle in die Kommunikation einschleichen können.

OpenPGP Best Practices - riseup.net
We have gathered here a lot of information about configuring GnuPG. There are detailed explanations for each configuration suggestion. Many of these changes require you to make changes to the GnuPG configuration file on your machine located at ~/.gnupg/gpg.conf. For your convenience, all the suggested changes to the gpg.conf file are gathered in one place near the bottom of this page. We strongly encourage you to not blindly copy the file, but read the document and understand what the settings do.

SSH authentication with GnuPG and smart cards › NETWAYS Blog
Most system administrators know how to use key-based authentication with SSH. Some of the more obvious benefits include agent forwarding (i.e. being able to use your SSH key on a remote system) and not having to remember passwords. There are, however, a few issues with having your SSH key on a general-purpose computer: Malware can obtain an unencrypted copy of your private SSH key fairly easily. Also, while migrating your key to another system is fairly easy it’s virtually impossible to securely use your SSH key on another untrusted system (e.g. at a customer).

python-gnupg - A Python wrapper for GnuPG — Python Wrapper for GnuPG 0.4.0 documentation
The gnupg module allows Python programs to make use of the functionality provided by the GNU Privacy Guard (abbreviated GPG or GnuPG). Using this module, Python programs can encrypt and decrypt data, digitally sign documents and verify digital signatures, manage (generate, list and delete) encryption keys, using proven Public Key Infrastructure (PKI) encryption technology based on OpenPGP.

Inline PGP in E-mail is bad, Mm'kay?
This was written after one too many tiring discussion when someone wanted to support inline PGP in e-mail. The title was inspired by South Park. This is a live document, and your feedback will improve it. Contributions will be acknowledged. -==- This document assume some familiarity with e-mail message formats, MIME and PGP. -==- This document is based on my experience with actually implementing and supporting inline PGP in the real world, in the Gnus message user agent.

The Case for Short OpenPGP Key Validity Periods – Simon Josefsson's blog
I will explain how OpenPGP key expiration works; how to extend the expiration time of your key; and argue why having a relatively short validity period can be a good thing.

sig2dot GPG/PGP Keyring Graph Generator
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
