i need to use large integers of the size 1024 to 2048 in a cryptography project using C... are there any header files available which will make my work easier if not ... how do i hanlde these integers using structures ???
By handling i mean multiplication , exponentation , applying modulus function etc ...
most of the time i'll be using (x^y)(mod p) where the numbers are of the size 1024 to 2048 bits ...

Google "bignum C++".
could you please elaborate on ""bignum c++ "" ... can it handle REALLY large numbers ???
Yes, it can handle numbers as large as you like, but you need a library to help you.
Here's a "bignum" library.
