The idea and rsa source codes were in a directory old/ on the GNUPG site,
and may have problems. With GNUPG I can read PGP encrypted/signed files,
but the rsa/idea signatures produced by GNUPG are not readable by PGP.
A comment is always added despite the no-comments line in .gnupg/options.
Perhaps this is by design, to make everyone switch to gpg..
If someone more qualified at cryptography wants to package gnupg-nonfree
it's all yours. I was just experimenting. The licenses are pretty
restrictive, I'm not sure we can even distribute IDEA from the non-US ftp
site in Germany. The license doesn't mention Australia, so IDEA may not be
patented here. Europe, the U.S., and Japan are covered. "Freeware"
requires a license directly from the patent holders.

The code herein has been taken from:
Bruce Schneier: Applied Cryptography. John Wiley & Sons, 1996.
ISBN 0-471-11709-9. .
The IDEA algorithm is patented by Ascom Systec Ltd. of CH-5506 Maegenwil,
Switzerland, who allow it to be used on a royalty-free basis for certain
non-profit applications. Commercial users must obtain a license from the
company in order to use IDEA. IDEA may be used on a royalty-free basis under
the following conditions:
Free use for private purposes:
The free use of software containing the algorithm is strictly limited to non
revenue generating data transfer between private individuals, ie not serving
commercial purposes. Requests by freeware developers to obtain a
royalty-free license to spread an application program containing the
algorithm for non-commercial purposes must be directed to Ascom.
Special offer for shareware developers:
There is a special waiver for shareware developers. Such waiver eliminates
the upfront fees as well as royalties for the first US$10,000 gross sales of
a product containing the algorithm if and only if:
1. The product is being sold for a minimum of US$10 and a maximum of US$50.
2. The source code for the shareware is available to the public.
Special conditions for research projects:
The use of the algorithm in research projects is free provided that it serves
the purpose of such project and within the project duration. Any use of the
algorithm after the termination of a project including activities resulting
from a project and for purposes not directly related to the project requires
a license.
Ascom Tech requires the following notice to be included for freeware
products:
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.
Commercial purposes shall mean any revenue generating purpose including but
not limited to:
i) Using the algorithm for company internal purposes (subject to a site
license).
ii) Incorporating the algorithm into any software and distributing such
software and/or providing services relating thereto to others (subject to
a product license).
iii) Using a product containing the algorithm not covered by an IDEA license
(subject to an end user license).
All such end user license agreements are available exclusively from Ascom
Systec Ltd and may be requested via the WWW at http://www.ascom.ch/systec or
by email to idea@ascom.ch.
Use other than for commercial purposes is strictly limited to non-revenue
generating data transfer between private individuals. The use by government
agencies, non-profit organizations, etc is considered as use for commercial
purposes but may be subject to special conditions. Any misuse will be
prosecuted.
