haiti [hash]

Dictionary creation

# Pydictor
# https://www.github.com/landgrey/pydictor.git
pydictor.py -extend TERM --leet 0 1 2 11 21 --len 4 20

# Username generator
# https://github.com/benbusby/namebuster
namebuster https://example.com
namebuster "term1, term2"

Examples

# Numeric dictionary length 4
python3 pydictor.py -base d --len 4 4

# Capital letters dictionary length 4
python3 pydictor.py -base c --len 4 4

# Prepend word + digits 5 length
python3 pydictor.py --len 5 5 --head raj -base d

# Append word after digits 5 length
python3 pydictor.py --len 5 5 --tail raj -base d

# Permute chars in word
python3 pydictor.py -char raj

# Multiple permutations
python3 pydictor.py -chunk abc ABC 666 . _ @ "'"

# Dictionary based in word, added complexity 4 and fixed length
python pydictor.py -extend raj --level 4 --len 1 6

# Interactive mode
python3 pydictor.py --sedb

Options

-base dLc # Base digits, Lowercase letters and Capital letters
--encode b64 # Encode output

Examples

# Dictionary
hashcat -m 0 -a 0 hashfile dictionary.txt -O --user -o result.txt

# Dictionary + rules
hashcat -m 0 -w 3 -a 0 hashfile dictionary.txt -O -r haku34K.rule --user -o result.txt

# Mask bruteforce (length 1-8 A-Z a-z 0-9)
hashcat -m 0 -w 3 -a 3 hashfile ?1?1?1?1?1?1?1?1 --increment -1 --user ?l?d?u
hashcat -m 0 -w 3 -a 3 hashfile suffix?1?1?1 -i -1 --user ?l?d

# Modes
-a 0 = Dictionary (also with rules)
-a 3 = Bruteforce with mask 

# Max performance options
--force -O -w 3 --opencl-device-types 1,2

# Output results
-o result.txt

# Ignore usernames in hashfile
--user/--username

# Masks
?l = abcdefghijklmnopqrstuvwxyz
?u = ABCDEFGHIJKLMNOPQRSTUVWXYZ
?d = 0123456789
?s = «space»!"#$%&'()*+,-./:;<=>?@[\]^_`{|}~
?a = ?l?u?d?s
?b = 0x00 - 0xff
