• Cracking a custom hash with John the Ripper Help I am learning to crack some hashes and I decided to use John the Ripper to hep crack them. I crack some of the hashes but I was presented with a custom one that I don't know how to approach.
• I've encountered the following problems using John the Ripper. These are not problems with the tool itself, but inherent problems with pentesting and password cracking in general. Sometimes I stumble across hashes on a pentest, but don't recognise the format, don't know if it's supported by john, or whether there are multiple.
• John.exe Cracking Passwords. John the Ripper's primary modes to crack passwords are single crack mode, wordlist mode, and incremental. The single crack mode is the fastest and best mode if you have a full password file to crack. Wordlist mode compares the hash to a known list of potential password matches.

Dec 24, 2017 John the Ripper ('JtR') is one of those indispensable tools. It's a fast password cracker, available for Windows, and many flavours of Linux. It's incredibly versatile and can crack pretty well anything you throw at it. So let's test it out!

Introduction

John the Ripper (JTR) is a widely known and verified fast password cracker, available for Windows, DOS, BeOS, and OpenVMS and many flavours of Linux. It uses wordlists/dictionary to crack many different types of hashes including MD5, SHA, etc.

John the Ripper: Fast Password Cracker

This password cracking tool is free and Open Source, initially developed for the Unix operating system. But today it runs on fifteen different platforms. Its primary purpose is to detect weak Unix passwords. Besides several crypt(3) password hash types most commonly found on various Unix systems, supported out of the box are Windows LM hashes, and a lot of other hashes and ciphers in the community-enhanced version.

For those who rather use commercial version, John the Ripper is available for following platforms:

• Linux: John the Ripper Pro
• Mac OS X: John the Ripper Pro
• Windows: Hash Suite
• Android: Hash Suite Droid

John the Ripper offers two types of attacks:

• Dictionary: It takes text string samples from wordlist, which contains dictionary of real passwords that are cracked before, encrypting it in the same format as the password being examined (encryption algorithm/key), and comparing the output to the encrypted string. John can also perform word alterations.
• Brute force: It goes through all the possible plaintexts, hashing each one and then comparing it to the input hash. This method takes a long time to run, but it's precious for cracking password that doesn't appear in wordlist dictionary.

Features/Performance

• Feature-rich and fast password cracking tool, with several cracking modes.
• It allows you to define a custom cracking mode using the built-in compiler supporting a subset of C.
• You can use same cracker everywhere, since John is available for different platforms, with possibility to continue a cracking session started on another platform.
• This tool supports a lot of Unix crypt(3) hash types:
  • traditional DES-based,'bigcrypt',BSDI extended DES-based,FreeBSD MD5-based,OpenBSD Blowfish-based,Kerberos/AFS and Windows LM (DES-based),DES-based tripcodes.
• On Linux distributions with glibc 2.7+, John 1.7.6+ supports SHA-crypt hashes, with optional OpenMP parallelization (requires GCC 4.2+).
• On recent versions of Solaris, John 1.7.6+ supports and autodetects SHA-crypt and SunMD5 hashes, also with optional OpenMP parallelization (requires GCC 4.2+ or recent Sun Studio).
• John the Ripper Pro adds support for Windows NTLM (MD4-based) and Mac OS X 10.4+ salted SHA-1 hashes.
• 'Community enhanced' -jumbo versions add support for many more password hash types:
  • Windows NTLM (MD4-based), Mac OS X 10.4-10.6 salted SHA-1 hashes, Mac OS X 10.7 salted SHA-512 hashes, raw MD5 and SHA-1, arbitrary MD5-based 'web application' password hash types, hashes used by SQL database servers (MySQL, MS SQL, Oracle) and by some LDAP servers, several hash types used on OpenVMS, password hashes of the Eggdrop IRC bot, and lots of other hash types, as well as many non-hashes such as OpenSSH private keys, S/Key skeykeys files, Kerberos TGTs, PDF files, ZIP (classic PKZIP and WinZip/AES) and RAR archives.
• John the Ripper has its own highly optimized modules for different hash types and processor architectures.
