Mack the Knife is a modular password cracking framework which relies on heavy parallel computing on the GPU using Nvidia's CUDA technology. The name Mack the Knife comes from the protagonist from Bertolt Brecht's "The Threepenny Opera" and is supposed to be a reference to the well known password cracker John the Ripper.
