+GPG-Addon Docu
+==============
+
+the gpgpaddon package contains 
+(1) additional GnuPG modules which were left out from the standard 
+    GnuPG package for certain reasons
+(2) gpg-2comp wrapper to enable using GnuPG for creating and checking PGP2
+    compatible messages
+
+(1) Modules
+-----------
+
+Modules for GnuPG with licensing or security issues.
+Useful for interaction with PGP2, see end of file.
+Please read the following notes carefully!
+
+IDEA: 
+ Patented by Ascom Systec Ltd. of CH-5506 Maegenwil. Only freely usable
+ for certain non-profit purpose:
+ This software product contains the IDEA algorithm as described and claimed in
+ US patent 5,214,703, EPO patent 0482154 (covering Austria, France, Germany,
+ Italy, the Netherlands, Spain, Sweden, Switzerland, and the UK), and Japanese
+ patent application 508119/1991, "Device for the conversion of a digital block
+ and use of same" (hereinafter referred to as "the algorithm").  Any use of
+ the algorithm for commercial purposes is thus subject to a license from Ascom
+ Systec Ltd. of CH-5506 Maegenwil (Switzerland), being the patentee and sole
+ owner of all rights, including the trademark IDEA.
+
+RIJNDAEL:
+ The winner of the NIST competition for a new free standard crypto algorithm
+ (as successor of DES).
+ Rijndael has been integrated into GnuPG-1.0.4 and is therefore not built
+ into this package any more.
+
+RSA:  
+ ATTENTION: This code should not have been exported _to_ the United 
+ States without a license agreement with PKP prior to Sept. 20, 2000, as it
+ was encumbered by U.S. patent #4,405,829.
+ The RSA support now went into GnuPG-1.0.3 and is therefore not in this
+ package any more.
+
+RSAREF: 
+ This module is Copyright (c) 1999 Jason Gunthorpe <jgg@non-us.debian.org>
+ and is placed into the public domain, do with it what you will. It
+ comes with no warrenty express or implied.
+ RSAREF is limited in key size and in the coding of the encrypted data.
+ This module isn't terribly great as RSAREF has no concept of secure
+ memory so the secret key and the symmetric cipher are written to
+ insecure memory in several places in this code and within the RSAREF
+ lib.
+ NOT CURRENTLY BUILT.
+
+SKIPJACK:
+ GPL - but not recommended for use, as it's unclear whether it's safe.
+
+3DES:
+ An alternative 3DES implementation
+ Requires the openssl or Eric Young's ssleay library.
+ NOT CURRENTLY BUILT.
+
+
+Authors:
+    Werner Koch <werner.koch@guug.de>
+     and others
+
+
+(2) PGP2 interaction
+--------------------
+If you are allowed to use IDEA, then there's good news for you:
+With these modules, there's a painless migration path from PGP2 to GPG for
+you. (PGP5 does not show any problems in this respect.)
+I created a wrapper named gpg-compat and placed it into /usr/bin:
+#!/bin/sh
+exec gpg --load-extension idea --allow-non-selfsigned-uid $*
+
+However, this simple wrapper only allows to decrypt, check signatures and
+encrypt for PGP2. It does not allow automatic encryption for PGP2 nor both
+PGP2 encryption and signing. For this the gpg-2comp perl script from Gero
+Treuner has been put into /usr/bin/gpg-2comp. Please read the docu
+README.gpg-2comp. 
+You need to configure your gpg-2copm by creating a ~/.gpg-2comprc file. You
+may use the sample file for this.
+
+The following works with both scripts ...
+
+Now import your PGP2 keys into your GPG keyring:
+gpg-compat --import ~/.pgp/pubring.pgp
+gpg-compat --import ~/.pgp/secring.pgp
+
+One caveat: A few keys may not be acceptable to gpg.
+You may want to add signatures, e.g. sign your new GPG key with your old PGP2
+key and vice versa. This is possible:
+
+gpg-2comp --default-key 0x<PGP2KEYID> --edit-key 0x<GPGKEYID>
+and vice versa.
+
+Tell your mutt-0.9xi ot mutt-1.0i to use gpg-2comp:
+set pgp_gpg=gpg-2comp
+For mutt-1.2i, you may use the gpg.rc distributed with mutt and enable the
+gpg-2comp settings. More easily: use the gpg.rc you find here.
+A hint: Don't unset pgp_strict_encoding with mutt-1.2i, even if braindead
+MUAs fail to display quoted-printable (aka quoted-unreadable) and your 
+friends complain.
+
+But please tell your friends to also fully move to GPG and avoid patented
+algorithms, even if you consider these patents to be bogus. You don't rule
+the world, do you?
+
+							Your SuSE team.

+Info for users of previous versions of gpgaddon
+-----------------------------------------------
+
+The scripts have been renamed. The gpg-2comp script is now installed by that
+name (was: gpg-compat) and the simple wrapper has the name gpg-compat (was:
+gpg-compat.old), now.
+Please re-read the instructions on how to set up your mutt config.
+Sorry about this!
