A few years ago while adding strong cryptography to an application, I used a

library called CryptoLib form ATT (now Lucent) that could handle integers

with thousands of bits. I don't know if it is sill available. I just did a

search for "large integer arithmetic" (without the quotes) on Google and got

lots of links to libraries.
