John the Ripper

John the Ripperis a fast password cracker, currently available for many flavors of Unix, Windows, DOS, BeOS, and OpenVMS. Its primary purpose is to detect weak Unix passwords, although Windows LM hashesand a number of other password hash types are supported as well. John the Ripper is free and Open Source software, distributed primarily in source code form.
John the Ripper Pro builds upon the free John the Ripper to deliver a commercial product better tailored for specific operating systems. It is distributed primarily in the form of "native" packages for the target operating systems. 

The following Linux distributions are supported:
  • Red Hat Enterprise Linux and CentOS (any version) for x86 and x86-64
  • Fedora Core (any version) for x86 and x86-64
  • Red Hat Linux 7.0 and above
    This is the old product name and version numbering that Red Hat used many years ago - yes, many of these ancient versions are in fact supported
  • SUSE Linux 7.1 and above for x86 and x86-64
  • Mandriva Linux (any version) for x86 and x86-64
  • Ubuntu (any version) for x86 and x86-64
  • Slackware 8.1 and above
  • Openwall GNU/*/Linux 1.1 and above
  • any other distribution with RPM 3+, glibc 2.1+, Linux kernel 2.4.0+ that is capable of running executables for x86 (i386) or/and x86-64 (x86_64)
The following password hash types are currently supported (and more are planned):
  • Traditional DES-based Unix crypt(3) - most commercial Unix systems (Solaris, AIX, ...), Mac OS X 10.2, ancient Linux and *BSD
  • "bigcrypt" - HP-UX, Tru64 / Digital Unix / OSF/1
  • BSDI-style extended DES-based crypt(3) - BSD/OS, *BSD (non-default)
  • FreeBSD-style MD5-based crypt(3) - most Linux, FreeBSD, NetBSD, Cisco IOS, OpenBSD (non-default)
  • OpenBSD-style Blowfish-based crypt(3)- OpenBSD, some Linux, other *BSD and Solaris 10 (non-default)
  • Kerberos AFS DES-based hashes
  • LM (LanMan) DES-based hashes - Windows NT/2000/XP/2003, Mac OS X 10.3
  • NTLM MD4-based hashes - Windows NT/2000/XP/2003/Vista (new in 1.7.3 Pro)
  • Mac OS X 10.4 - 10.6 salted SHA-1 hashes (new in 1.7.3 Pro)
