Is rainbow table A software?
A rainbow table is a listing of all possible plaintext permutations of encrypted passwords specific to a given hash algorithm. Rainbow tables are often used by password cracking software for network security attacks.
How are rainbow tables created?
Rainbow tables are created by precomputing the hash representation of passwords, and creating a lookup table to accelerate the process of checking for weak passwords.
How long does a rainbow table take?
When using a more modern algorithm such as sha256, John the Ripper can do a rather measly 200,000 hashes per second. At that rate it would take 3 minutes to generate a 4 character rainbow table.
Which is the program that generates rainbow tables?
This document explains the rtgen and rtsort programs. The rtgen program generate rainbow tables based on parameters specified by user, and the rtsort program post processing the rainbow tables to enable fast lookup. After the two steps above, rainbow tables can be used to crack hashes with rcrack program.
What kind of hash algorithm does rainbow table use?
Rainbow table of LM, NTLM, MD5, SHA1, SHA256 and customizable hash algorithms Rainbow table of customizable charset GPU acceleration with AMD GPUs (OpenCL technology) GPU acceleration with NVIDIA GPUs (CUDA technology) GPU acceleration with multiple GPUs
What can rcracki _ Mt do for a rainbow table?
Rcracki_mt can be used to perform a rainbow table attack on password hashes. It is intended for indexed&perfected rainbow tables, mainly generated by the distributed project www.freerainbowtables.com
How to pause rainbow table generation and sort?
CPU will be busy computing rainbow chains. On system with multi-core processor, all cores are fully utilized. To pause table generation, just press Ctrl+C and rtgen program will exit. Next time if the rtgen program is executed with exactly same parameters, table generation is resumed.
