John the Ripper Pro password cracker for Linux
John the Ripper
is a fast password cracker, available for many operating systems.
Its primary purpose is to detect weak Unix passwords,
although Windows LM hashes
and 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.
John the Ripper Pro is
available for a number of operating systems.
This web page describes the Linux revision of John the Ripper Pro.
On Linux, the features currently specific to Pro versions are:
- Pre-built and well-tested native packages (RPM),
which may be installed with a single command - no need to compile
Even though these are RPM rather than deb packages,
instructions for easy installation on Debian and Ubuntu
are also included
- Separate packages for newer 64-bit capable systems (x86_64)
and older 32-bit systems (i686)
- Automatic detection of multi-core CPUs and use of multi-threading,
with transparent fallback
to a single-threaded build on single-core machines (or VMs)
or when use of multiple sub-processes instead of threads is requested
(with the --fork=N option)
- Automatic detection of processor architecture extensions:
AMD XOP, Intel AVX, SSE2, MMX for
much faster processing at some hash types,
with transparent fallback on older CPUs
- A large multilingual wordlist
(5,014,869 entries, 55 MB uncompressed) is included in the package,
and John the Ripper is pre-configured for its use
- The included documentation is revised to be specific
for the given package on Linux rather than generic,
making it easier to understand
- As a bonus, the full source code sufficient to rebuild the
package is also provided (can be downloaded separately)

Additionally, you will be able to download a previous version of
John the Ripper Pro, which supports even older distributions:
- Red Hat Enterprise Linux and CentOS (any version)
- Fedora Core (any version)
- 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
- Ubuntu (any version)
- SUSE Linux 7.1 and above
- Mandriva (any version)
- 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+
The following password hash types are currently supported in the latest version
(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)
- older Linux, FreeBSD, NetBSD, Cisco IOS, OpenBSD (non-default)
Also supported are Apache httpd "apr1" hashes
(these are a variation of the above)
- OpenBSD-style Blowfish-based crypt(3)
- OpenBSD, some Linux, other *BSD and Solaris 10+ (non-default)
- SHA-crypt (sha512crypt and sha256crypt) - newer Linux
These are supported when running on a system with glibc 2.7+ (any recent system)
- Kerberos AFS DES-based hashes
- LM (LanMan) DES-based hashes -
Windows NT/2000/XP/2003, Mac OS X 10.3
