I assume your question is: Is the IDEA algorithm patented? It was patented and this was one or the main reasons to develop GnuPG as the free PGP replacement. Meanwhile the patent expired: * Patents on IDEA have expired: * Europe: EP0482154 on 2011-05-16, * Japan: JP3225440 on 2011-05-16, * U.S.: 5,214,703 on 2012-01-07. Thus if you have to decrypt old data you may now use a decent GnuPG versions to do that (1.4.13 or 2.x along an appropriate Libgcrypt version). Salam-Shalom, Werner -- Die Gedanken sind frei. Ausnahmen regelt ein Bundesgesetz. _______________________________________________ Gnupg-users mailing list Gnupg-users@gnupg.org http://lists.gnupg.org/mailman/listinfo/gnupg-users
