Soul Posted March 13, 2008 Posted March 13, 2008 (edited) Hi people , I wrote a few ciphers in (M)ASM , these are:GRAIN,ICE,KASUMI,MERCY,MESH,PLAYFAIR.My request:can anybody test it on his OS ? I have tested it on W2k but maybe it would not work on other OS. Edit: Ok , i dropped the ripped ciphers out and I will revise them. Edit2: -revised version of KASUMI -new cipher: Camellia Edit3: -new cipher: FROG Edited April 28, 2008 by Soul

Loki Posted March 14, 2008 Posted March 14, 2008 Suggests to me that its ripped from some other app? Perhaps CrypTool?Did you code these or are they pulled from somewhere else?
Ufo-Pu55y Posted March 14, 2008 Posted March 14, 2008 (edited) He gives the info himself: Quote Ripped from C-SourceRegards, Soul Tho it's more like from C assembly than from source.Yes I think it could (should) be cleaned a bit more. More than ever, if routines are short. Often it's not hard to even optimize em then. Nevertheless thanks for the efforts Hard to find sources for uncommon crypt n hash ****..

Soul Posted March 14, 2008 Author Posted March 14, 2008 (edited) Quote pretty bad coding m8, u sure u know what you're doing...? Quote He gives the info himself:QUOTE Ripped from C-Source Regards, Soul Thx Yeah it's correct , 3 of the sources are 100% ripped (KASUMI,MERCY,GRAIN) , the other (ICE,MESH,PLAYFAIR) are made by me himself.But thanks for response. ^^ Edited March 14, 2008 by Soul
evlncrn8 Posted March 14, 2008 Posted March 14, 2008 (edited) ripped pretty damned badly... nice idea, but i'd seriously revise the code to show you actually have an understanding of the ciphers / cypher (depending on your personal spelling preference) and havent just kludged this together to look leet.. the ripping of c->asm can be done considerably better... out of curiousity, what program did you use to do the ripping?

Well , you said it , it was a idea and 3 of them are ripped only.I used OllyDbg nothing more.But if you wish , you can make it better Edited March 14, 2008 by Soul
