Accessing ELF of the executable file ?
 

hi guys
this is vishal.
i am using linux kernel 2.6.10 on FEDORA CORE 3.To
check the integriety of the executables i
want to keep the hash of the executables. Now
insted of using entire contents of the executables
i am trying to calculate the hash of elf of
the executable.
So plz anyone can tell me how i can access elf of
executable?

Again what i am doing is possible only with hash of
elf? Or am i on wrong track?

Your sols. r always welcome.

Maybe these links help:
http://elfsh.segfault.net/
http://directory.fsf.org/libs/misc/libelf.html

(both are available in debian, don't know for other distro's)

Thanks HKo

i have gone through the sites u mentioned.
Is there any utility tool to access the elf information?
and I am still confused .. what will i need from eldf headers to calculate hash of the executables to ensure the integriety of the executables?

That would be the first link I guess.
