# hashcat > Fast and advanced password recovery tool. > More information: . - Perform a brute-force attack (mode 3) with the default hashcat mask: `hashcat --hash-type {{hash_type_id}} --attack-mode {{3}} {{hash_value}}` - Perform a brute-force attack (mode 3) with a known pattern of 4 digits: `hashcat --hash-type {{hash_type_id}} --attack-mode {{3}} {{hash_value}} "{{?d?d?d?d}}"` - Perform a brute-force attack (mode 3) using at most 8 of all printable ASCII characters: `hashcat --hash-type {{hash_type_id}} --attack-mode {{3}} --increment {{hash_value}} "{{?a?a?a?a?a?a?a?a}}"` - Perform a dictionary attack (mode 0) using the RockYou wordlist of a Kali Linux box: `hashcat --hash-type {{hash_type_id}} --attack-mode {{0}} {{hash_value}} {{/usr/share/wordlists/rockyou.txt}}` - Perform a rule-based dictionary attack (mode 0) using the RockYou wordlist mutated with common password variations: `hashcat --hash-type {{hash_type_id}} --attack-mode {{0}} --rules-file {{/usr/share/hashcat/rules/best64.rule}} {{hash_value}} {{/usr/share/wordlists/rockyou.txt}}` - Perform a combination attack (mode 1) using the concatenation of words from two different custom dictionaries: `hashcat --hash-type {{hash_type_id}} --attack-mode {{1}} {{hash_value}} {{/path/to/dictionary1.txt}} {{/path/to/dictionary2.txt}}` - Show result of an already cracked hash: `hashcat --show {{hash_value}}`
