C++ BigInt

Is there a C++ BigInt library for Linux? I have Googled plenty of times, to no avail.

Also note: This library must work with hexadecimal numbers.

Maybe 'Boost' library ?

And how do you exactly describe "hexadecimal numbers" You insist the numbers should be represented as ASCII hex strings, i.e. consist of ASCII characters 0-9a-f ?

The OP probably means it needs to be able to take numbers in ASCII 0-F and print numbers in ASCII 0-F.

Hi -

Does this help:

C++ BigInt Class Library

PS:
Manipulating arbitrarily large integers is one thing. Formatted printing of such integers is another. You can definitely do the former with the above SourceForge project; I believe it should be fairly easy to do the latter as well.

What I want to accomplish is brute force of 128-bit hexadecimal numbers. In other words: Using variables to set a range of numbers with a lower limit and upper limit, for the purpose of guessing numbers in between. This in order to, for instance, crack devices for the purpose of jailbreaking them.
