Of cource, it does not depend to the Matthew Kwan's S-boxes expressions. Kwan's code was designed for a general RISC processors (with having 2-source operand logical operation). To get my own code, I used the automatic code generator, which optimized by me for MUX and some 2-source operand instructions. Perhaps, the generator is more specialized than Marc Bevand's sbox-gen. (The idea of Bevand is not the best though thinks it is wonderful as the method for the request of the shortest number of gates.) > Would you like your code to be integrated into the official JtR, into > the jumbo patch, or not at all? > > For the official JtR, your use of a BSD license is problematic; I'd > prefer public domain or an even more relaxed license, obviously > compatible with both BSD and GPL and not requiring anything extra. > http://www.fsf.org/licensing/licenses/ says that the 2-clause BSD > license is GPL-compatible, yet I think it imposes extra restrictions - > namely, it requires that it be "reproduced" on copies of the software. > So merely including the GNU GPL with the software (or referring to it) > becomes no longer sufficient. It was careless. I will change to a dual license of BSDL/GPL, and to GPL version here: http://download.kousaku.in/trip/BitsliceDES-sboxes-20081222-GPL.zip (The code for Cell SPU is bundled) -- To unsubscribe, e-mail john-users-unsubscribe@...ts.openwall.com and reply to the automated confirmation request that will be sent to you.
