In the source code of the package my team is managing there is this one file.
I'm wondering whether it is DFSG-free and weather GPL v2 only code can link it with/(out) exception. Here is the full copyright statement /* sapphire.cpp -- the Saphire II stream cipher class. Dedicated to the Public Domain the author and inventor: (Michael Paul Johnson). This code comes with no warranty. Use it at your own risk. Ported from the Pascal implementation of the Sapphire Stream Cipher 9 December 1994. Added hash pre- and post-processing 27 December 1994. Modified initialization to make index variables key dependent, made the output function more resistant to cryptanalysis, and renamed to Sapphire II 2 January 1995 */ -- With best regards Dmitrijs Ledkovs (for short Dima), Ледков Дмитрий Юрьевич -- To UNSUBSCRIBE, email to debian-legal-requ...@lists.debian.org with a subject of "unsubscribe".
