Sorry for the delay in reply. The paper comes across as an undergrad posting, not terrible, just naive. I infer that this paper was posted in 2004. The minimalist "strstr" amounts to: Code: char *s...

My apologies; should have added that I'm certainly no expert in low-level algorithm optimization. If it's not too much trouble do you mind going into more detail concerning the deficiencies you've not...

Might I humbly suggest you look at that paper but not take it seriously --- somebody post a request if you want me to go into detail as to how it's deficient. A definitive read on modern search algori...

God I had a hell of a time trying to compile openSSL, finally realised that the win32 wesion available online included the MinGW libraries. It's all working now however using the SSL code i am still ...
Programming • Re: [ASM] Calling functions without importing them 4 Jul 2013 | 10:39 pm
In the context that strcmp is called, it looks like the first argument is the current function name being parsed in the kernel32 EAT, and the second argument is the name of the function to import. St...

ok thanks :) just one last question, what it contains this? Code: push ebx<-- mov eax, [esp + 0x08]<-- mov ebx, [esp + 0x0C]<-- is kernel32 base address and function name? Code...

The unsecure connection code works fine, but the secure connection does not. I copy exactly what you posted. Do you miss something ? Statistics: Posted by Guest — Thu Jun 27, 2013 7:40 am

Looks like it's just comparing bytes from the strings pointed to by the first and second arguments on the stack, and incrementing them, respectively. Statistics: Posted by irql — Mon Jun 24, 2013 4:3...

hi somebody can explain me, what it does this? Code: ; ------------------------------------------------- ; int strcmp(char *a, char *b) ; returns 1 if the two strings are equal, 0 if not ; --------...
Programming • Re: Fast string comparison 20 Jun 2013 | 03:05 am
I believe the algorithm you've described is actually better termed as "string search" instead of comparison. Anyway I would first like to point out that, starting with glibc 2.10 (iirc), the string s...
