The application is portable, meaning that you don't need to install it on the target computer so that you can use it.

Such important data might be passwords or sensitive personal information.

The principle behind the rainbow table attack is that the perpetrator attempts to decrypt a series of passwords that are stored within a database by using a rainbow hash table in order to do so.Ī rainbow table is a hash function that is widely used in cryptography for storing various bits of important data inside a database.

To get optimal performance, all GPUs need be of same model.RainbowCrack is a lightweight, specialized software solution that was developed to help advanced computer users decode (decrypt) various password hashes by making use of what is widely know as 'Rainbow table attack.' GPU acceleration with multiple GPUs is supported.

The rcrack program always read data from hard disk sequentially.

Windows operating system natively support software RAID 0 called 'striped volume'. We suggest put rainbow tables in RAID 0 volume with multiple hard disks. Hard Diskīecause rainbow table must be loaded from hard disk to memory to look up and some rainbow table set can be as large as hundreds of GB, hard disk performance becomes a very important factor to achieve overall good hash cracking performance. Larger memory always help to improve performance when searching large rainbow tables. Performance Tips Memory RequirementĤ GB memory is minimal and 8 GB or more memory is recommended. When rainbow tables are specified, hash cracking will start. All rainbow table groups are defined in configuration file group.txt. Select 'Search Rainbow Tables Group ' to search rainbow tables in multiple directories sequentially. Select 'Search Rainbow Tables in Directory.' to search all rainbow tables in a directory. Select 'Search Rainbow Tables.' to search individual rainbow tables. Rcrack_cuda c: t -ntlm pwdump_file Rainbow Table Lookup with rcrack_gui/rcrack_cl_amd_gui/rcrack_cuda_gui Program Step 1: Load the Hashes Step 2: Specify the Rainbow Tables to be Searched

To load and crack NTLM hashes from pwdump file: To load and crack LM hashes from pwdump file: In the example above, the rcrack/rcrack_cl_amd/rcrack_cuda program will lookup rainbow tables in c: t1 and c: t2 directories sequentially.

Rcrack_cuda c: t1 c: t2 -l hash_list_file Rcrack_cl_amd c: t1 c: t2 -l hash_list_file To lookup rainbow tables in multiple directories: In the example above, hash_list_file is a text file with each hash in one line. Rainbow Table Lookup with rcrack/rcrack_cl_amd/rcrack_cuda Program General UseĪssume rainbow tables are in directory c: t. Rainbow tables used by rcrack program must already be sorted with rtsort program, and optionally converted to. Six similar programs are available: Program The rcrack program lookup existing rainbow tables for the plaintext of user supplied hash. This document explains the rcrack program.
