Erik has already posted the most appropriate link: http://tmkk.hp.infoseek.co.jp/tripper/index_e.html VecTripper_20090729.tar.bz2 has the source code, and it reuses and even enhances code from JtR. In fact, I suspect that Dango-Chu's DES S-boxes for AltiVec, currently included in JtR 1.7.6 as sboxes-s.c, were originally created primarily with tripcodes in mind. That web page also has links to other implementations. Finally, this lengthy multi-year thread: http://wakaba.c3.cx/soc/kareha.pl/1100499906 has many links to various implementations, intermixed with garbage and spam comments... Good luck! Alexander
