SYNOPSIS
rtgen algorithm charset min max index chainlen chainnum part
DESCRIPTION
rtgen generates rainbow tables for password cracking. Rainbow tables are precomputed tables for reversing cryptographic hash functions. Part of RainbowCrack.
PARAMETERS
algorithm
Hash type (md5, sha1, ntlm, lm).charset
Character set (loweralpha, numeric, etc.).min_len
Minimum password length.max_len
Maximum password length.table_index
Table index for multiple tables.chain_len
Reduction chain length.chain_num
Number of chains.part_index
Part index.
EXAMPLES
$ # Generate MD5 lowercase table
rtgen md5 loweralpha 1 7 0 2400 67108864 0
# NTLM numeric
rtgen ntlm numeric 1 8 0 2400 33554432 0
# Sort generated table
rtsort md5_loweralpha#1-7_0_2400x67108864_0.rt
# Use with rcrack
rcrack . -h 5d41402abc4b2a76b9719d911017c592
rtgen md5 loweralpha 1 7 0 2400 67108864 0
# NTLM numeric
