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

LEAVE

RETN

KeyInitialization ENDP

pretty bad coding m8, u sure u know what you're doing...?

firstly its a proc that takes params.. so it should end in a ret, considering it has an ebp frame

leave isnt needed either.. and the add esp,4 at the top makes no sense what so ever

should be like...

KeyInitialization proc cache:DWORD,szKey:DWORD,szKeylength:DWORD,szIVlength:DWORD

MOV EAX, [cache]

MOV ECX, [szKey]

MOV EDX, [szKeylength]

MOV DWORD PTR DS:[EAX+280h],ECX

MOV ECX,DWORD PTR SS:[szIVlength]

MOV DWORD PTR DS:[EAX+284h],EDX

MOV DWORD PTR DS:[EAX+288h],ECX

RET

KeyInitialization ENDP

looks better.. no?

Suggests to me that its ripped from some other app? Perhaps CrypTool?

Did you code these or are they pulled from somewhere else?

He gives the info himself:

Ripped from C-Source

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 ****..

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. ^^

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
