AnnouncerPlugin/MessageEncryption

 Beware, that this is by now no code but pure concept and subject to change a lot, before public release of the code. As with current code for AnnouncerPlugin there'll be DEBUG logging embed into all operations mentioned above.
 
+==== Behind current development scope ====
+There is a [t:wiki:TracDev/Proposals/Announcer proposal] to replace current Trac Notification system with AnnouncerPlugin. This will make the effort for a really clean solution even more urgent.
+
+Consider [https://subtrac.sara.nl/oss/email2trac/ticket/186 cryptography related features] for EmailtoTracScript ([https://subtrac.sara.nl/oss/email2trac current home outside of Tack-Hacks]). It could be interesting i.e. to allow only e-mails with valid signature from known senders to pass, fighting spam at another level.

 ==== Q&A ====
  ?: ''Is it right that different users will have different keys?  If so we can add configuration to the user's preference page.  We could have a big textbox for GPG key and if they have one entered, then use encryption.

+==== Available interfaces with GnuPG ====
 To make it more difficult for me to start I've found not one but several candidates for interacting with GnuPG from Python (http://wiki.python.org/moin/GnuPrivacyGuard has a listing with some more comments):

+==== The choice: python-gnupg ====
+'''python-gnupg''' was tested, !PyMe a little too. It became clear, that python-gnupg just worked without much hassle. Anything else had more dependencies and was more complicated i.e. by introducing GPGME. This applies to !PyMe as well as PyGPGME. GnuPGInterface, OpenPGP, cryptlib where skipped right after the initial interface research.
