Hashcat

• “World’s fastest password cracker”
• used to crack hashes
  It allows you to use graphical processing units (GPUs) to accelerate the password-cracking process.
• Hashcat comes with Kali Linux and other penetration testing Linux distributions. You can also download it from https://hashcat.net/hashcat ↗.

Basic Usage#

hashcat -m <hash_type> -a <attack_mode> hashfile wordlist

• -m specifies hash type. Check the official documentation (man hashcat) and example page ↗ to find the hash type code to use.
  • 0 : md5
  • 100 : SHA1
  • 1000 : NTLM
  • 3200 : bcrypt
  • 1400 : sha2-256
  • 1800 : sha512
• -a specifies attack mode
  • 0 = Straight
  • 1 = Combination
  • 3 = Brute-force
  • 6 = Hybrid Wordlist + Mask
  • 7 = Hybrid Mask + Wordlist
• -o specifies the output file

eg: hashcat -m 0 -a 0 -o cracked.txt hashes.txt /usr/share/wordlist/rockyou.txt
