John the Ripper -- Password Cracker=====================================John the Ripper is a UNIX password cracker, currently available for UNIX,DOS, WinNT/Win95. Version 1.5 has been tested with Linux x86/Alpha/SPARC,FreeBSD x86, OpenBSD x86, Solaris 2.x SPARC and x86, Digital UNIX. There'salso a generic make target that should work on most other UNIX systems.The DOS and Win32 ports are done with DJGPP and Cygnus Developer's Kit,respectively. How to Install----------------See doc/INSTALL for information on installing John on your system. How to Use------------To run John, you need to supply it with some password files, and specify acracking mode, like this, using the "single crack" mode, and assuming thatpasswd is a copy of your password file:	john -single passwdand then, with a wordlist:	john -wordfile:/usr/dict/words -rules passwdCracked passwords will be printed to the terminal and saved in file called~/john.pot (in this text '~' means John's "home directory", that is, thedirectory you installed John's binary in). This file is also used not toload passwords that you already cracked, when you run John the next time.To retrieve the cracked passwords, run:	john -show passwdWhile cracking, you can press any key for status, or Ctrl+C to abort thesession, saving point information to a file (~/restore by default). By theway, if you press Ctrl+C twice John will abort immediately without saving.The point information is also saved every 10 minutes (see src/params.h) incase of a crash. To continue an interrupted session, run:	john -restoreAnyway, you probably should have a look at doc/OPTIONS for a list of allthe command line options, and at doc/EXAMPLES for more John usage exampleswith other cracking modes. Features and Performance--------------------------John the Ripper is designed to be both powerful and fast. It combinesseveral cracking modes in one program, and is fully configurable for yourparticular needs (you can even define a custom cracking mode using thebuilt-in compiler supporting a subset of C). Also, John is available forseveral different platforms, which enables you to use the same crackereverywhere (for example even continue a cracking session that you startedon another platform).Out of the box, John supports (and autodetects) the following ciphertextformats: standard and double-length DES-based, BSDI's extended DES-based,FreeBSD's (and not only) MD5-based, and OpenBSD's Blowfish-based.Unlike other crackers, John doesn't use a crypt(3)-style routine. Instead,it has its own highly optimized modules for different ciphertext formatsand architectures. Some of the algorithms used couldn't be implemented ina crypt(3)-style routine: they require a more powerful interface (bitsliceDES is an example). Additionally, there're assembly routines for severalprocessors and architectures (special Intel Pentium version, x86 with MMX,generic x86, Alpha EV4, SPARC V8).
