Wisecracker is a high performance distributed cryptanalysis framework that leverages GPUs and multiple CPUs. It allows security researchers to write their own cryptanalysis tools that can distribute brute-force cryptanalysis work across multiple systems with multiple multi-core processors and GPUs. Security researchers can also use the sample tools provided out-of-the-box. The differentiating aspect of Wisecracker is that it uses OpenCL and MPI together to distribute the work across multiple systems, each having multiple CPUs and/or GPUs.
Bletchley is a real-world cryptanalysis framework. It was created to assist with the detection, analysis, and exploitation of cryptographic flaws and aims to help automate the tedious aspects of this analysis while leaving the security expert in control of the process. It features automated token encoding detection (36 encoding variants), passive ciphertext block length and repetition analysis, a script generator for efficient automation of HTTP requests, and a flexible, multithreaded padding oracle attack library with CBC-R support.
