I envision these tutorials as step-by-step guides or examples for specific use cases - e.g., auditing passwords on a Windows system (that's one tutorial), then auditing passwords from various Unix-like systems and Windows on a Linux system (that's another tutorial). In Microsoft Windows user account password and information are stored in a file called SAM. jumbo versions add support for hundreds of additional hash and cipher types, including fast built-in implementations of SHA-crypt and SunMD5, Windows NTLM (.

There's no need to pipe a wordlist to anything, because starting with hashcat 4.0.0, you can skip aircrack-ng entirely, and directly crack a WPA2 PSK with hashcat (using -m 2500): $ hashcat -quiet -a 3 -m 2500 hashcat.hccapx hash?l?l?l?sĪ895f7d62ccc3e892fa9e9f9146232c1:aef50f22801c: (wrapped)ĩ87bdcf9f950:8381533406003807685881523:hashcat!

Press 'q' or Ctrl-C to abort, almost any other key for statusĪnd for what it's worth, you can also pipe hashcat output to another tool, using hashcat's -stdout option, following suggestion: $ hashcat -a 3 -1 02 091?1?d?d?d?d?d?d -stdout | head Here's how to do it with john (the "jumbo" version), using head to just show the first ten lines of output: $ john -1='02' -mask=091?1?d?d?d?d?d?d -stdout | head
