This is an extremely slow but working Visual Basic implementation of the 256-bit Serpent algorithm. Serpent was a finalist for AES and appears to be a very secure powerful algorithm. The C implementation is by far the fastest and most efficient. Since Visual Basic is bogged down by memory problems and lacks the power that C provides, high level speeds for this algorithm may never be achieved in Visual Basic. It is an excellent academic resource for all you budding cryptographers and security minded people though it is not recommended for commercial use.
