Does any of the reversers here know the cipher of this code snippet?
Code:
00DFC1DB | C1CD 16 | ror ebp,16 |
00DFC1DE | 33EB | xor ebp,ebx |
00DFC1E0 | C1CB 0B | ror ebx,B |
00DFC1E3 | 33EB | xor ebp,ebx |
00DFC1E5 | 03C5 | add eax,ebp |
00DFC1E7 | 894424 20 | mov dword ptr ss:[esp+20],eax |
00DFC1EB | 8B7C24 14 | mov edi,dword ptr ss:[esp+14] |
00DFC1EF | 337C24 18 | xor edi,dword ptr ss:[esp+18] |
00DFC1F3 | 23FA | and edi,edx |
00DFC1F5 | 337C24 18 | xor edi,dword ptr ss:[esp+18] |
00DFC1F9 | 8BEA | mov ebp,edx |
00DFC1FB | C1CA 06 | ror edx,6 |
00DFC1FE | C1CD 19 | ror ebp,19 |
00DFC201 | 037E 04 | add edi,dword ptr ds:[esi+4] |
00DFC204 | 037C24 5C | add edi,dword ptr ss:[esp+5C] |
00DFC208 | 037C24 1C | add edi,dword ptr ss:[esp+1C] |
00DFC20C | 33EA | xor ebp,edx |
00DFC20E | C1CA 05 | ror edx,5 |
00DFC211 | 33EA | xor ebp,edx |
This snippet with lot's of ROR commands is repeated may be 10 times or more...
I searched in whole cipher sources I own, not only ROR xxx, 16, ROR xxx, 22, >> 16, >> 22 and so on.
Nothing to be found!
