There is a new program `sharesecret' which enables you to split a secret into parts given a threshold. You can only recalculate the secret from the parts if you know more parts than threshold. The program is licences under the terms of the GNU General Puplic Licence (GPL) version 2 or later. See also http://www.mathematik.uni-ulm.de/m5/sk/sharesecret.html or ftp.mathematik.uni-ulm.de pub/soft/crypto/sharesecret_0.1.0.tar.gz for the sources or ftp.mathematik.uni-ulm.de pub/soft/crypto/sharesecret_0.1.0_i386.deb for the prepared Debian binary package. -- Stefan Karrmann
