HASH CRACK

Password Cracking Manual

I wrote a password cracking manual

Password cracking has always been this niche activity during a routine pentest. You collect some hashes, fire up John The Ripper or Hashcat, and use default settings with rules and some lame dictionary you pulled off the internet and hit <enter>. You recover a fair amount of the passwords but fail to make any real breakthroughs. After digging through forums and blog posts looking for tool usage, password analysis, and examples you apply some new trick only to forget it by the next pentest. After falling victim to this vicious cycle I decided to write a password cracking manual, HASH CRACK. I've also created a dedicated site to announce its availability and release future versions at hashcrack.io

Inspired by the Red Team Field Manual (RTFM) and its concise format, I set about researching and compiling the most common tools and their usage. Broken into sections to help the beginner and advanced security professional assist in their usage and understanding of the hash cracking process. Stripped of all the fluff and cuts right to the point with a simple sentence or two about each command and corresponding example usage.

The core tools covered in this manual are John The Ripper (JTR) and Hashcat since they are both absolutely amazing software with a robust community. So a convenient cheat sheet for each tool is included towards the front of the manual for easy reference.

Also included is a chapter called "Common Hash Examples" which lists the 25 most frequent hash types encountered during a pentest with examples in Hashcat and JTR. No nonsense and straight to the point to aid a security professional on the spot.
