RainbowCrack Project - Crack Hashes with Rainbow Tables

Introduction

RainbowCrack is a general propose implementation of Philippe Oechslin's faster time-memory trade-off technique. It cracks hashes with rainbow tables.

Features:

Full time-memory tradeoff tool suites, including rainbow table generation, sort, conversion and lookup
Support rainbow table of any hash algorithm
Support rainbow table of any charset
Support rainbow table in raw file format (.rt) and compact file format (.rtc)
Computation on multi-core processor support
Computation on GPU (via NVIDIA CUDA technology) support
Computation on multi-GPU (via NVIDIA CUDA technology) support
Runs on Windows XP 32-bit, Windows Vista 32-bit and Windows 7 32-bit
Command line and graphics user interface

A brute force hash cracker generate all possible plaintexts and compute the corresponding hashes on the fly, and then compare the hashes with the target hash. The plaintext is found if one of them match, otherwise the intermediate computation results are discarded.

A time-memory tradeoff hash cracker need a precomputation stage, at the time all plaintext/hash pair within the selected hash algorithm, charset, plaintext length range are computed and the results are stored in files called rainbow table. It is time consuming to do this kind of computation. Once the one time precomputation is finished, hashes within the table can be cracked with much better performance than a brute force cracker.

RainbowCrack for GPU

RainbowCrack for GPU software support GPUs from NVIDIA. By offloading computation task to GPU, the RainbowCrack for GPU software can be tens of times faster than CPU version.

The software package below is a demonstration and only smaller key spaces are supported.

RainbowCrack for GPU software with support of larger key space is available for purchase in this page, bundled with ready to work rainbow tables.
