CUDA Multiforcer - The world's fastest cross-platform MD4/MD5/NTLM cracking for Windows/Mac/Linux
World's fastest on a single hash or 100,000 hashes? No.. Fastest on a typical workload of tens to 100s of hashes? I believe so. World's fastest cross platform? As far as I know. Plenty of room for improvement? Sure. The first one planning to release the source? To my knowledge, yes.
