Hashcat

Usage

hashcat64.exe -a <ATTACK> -m <HASH FORMAT> -O --potfile-path <POT PATH> <HASH PATH> <WORDLIST PATH> -r <RULE PATH>

Additional Options:

Option Description
--username The hash file also contains username using format <USER>:<HASH>
-O Drasticly increases performance but can only crack passwords with less than 32 chars

Attack Types

Attack Option Description
Wordlist -a 0 use with derivation rules to increase efficiency
Combination -a 1 concatenate words from multiple wordlists
Mask (brute-force) -a 3 try all combination matching the mask

Masks

Wildcard Charset
?l Lowercase: [a-z]
?u Uppercase: [A-Z]
?d Digits: [0-9]
?s Specials: <space>!"#$%&'()*+,-./:;<=>@[]+ ...
?a All the aboves
?b Binaries: [0x00-0xff]
Increment

Add --increment to also match shorter password with the mask.

Example: ?d?d?d?d is equivalent to ?d, ?d?d, ?d?d?d and ?d?d?d?d

Groups

Create group of wildcards by using numerical placeholders.

Example: -1 ?l?u -2 ?d?s ?1?1?1?1?d?d?d?d?2
