The app can run in benchmark mode, which is a great way for any user to test their password strength for a limited amount of time. John the Ripper utilizes several methods for password testing and recovery – the most basic “single crack” method, and more advanced “incremental” and “external” that will use provided word library to try to filter and faster guess passwords. Most basic use involves typing the full name of the executable file, adding a few desired parameters and options, and then typing the file that contains passwords or hints for password recovery.
Thankfully to learn how to use the app to test and recover passwords, users only need to learn few command options and command syntax.
On the other hand, this GUI-less approach has made the app compatible with a wide variety of legacy PC configurations and can run on ALL versions of Windows OS. Since the user has to learn how to manage this app using only text commands and parameters, the John the Ripper app will most likely capture the attention of more seasoned PC users and technicians who can look past this disadvantage and focus only on the actual success rate of password recovery. Built from the ground up to be focused only on working with passwords, this versatile password utility is distributed without a graphical user interface and is therefore accessible only via a command window. The license has been relaxed.John the Ripper 64 bit is a decrypting and decoding utility built to test the strength of the user’s password as well as try to recover lost passwords using several built-in methodologies. The formats interface has been made more GPU-friendly. Reconstruction of ASCII encodings of LM hashes has been implemented to save RAM. Cracking of bcrypt on 32-bit x86 with GCC 4.2+ and DES-based tripcodes has been sped up. Bitmaps have been implemented for faster comparison of computed vs. Trivial parallel and distributed processing has been implemented with new -fork and -node options. More speed metrics have been added to the status line.
Changes: Incremental mode's efficiency has been improved, and its length and character set limitations in default builds have been lifted.
On top of this, many other hash types are added with contributed patches, and some are added in John the Ripper Pro. It supports several crypt(3) password hash types commonly found on Unix systems, as well as Windows LM hashes. Its primary purpose is to detect weak Unix passwords. John the Ripper is a fast password cracker, currently available for many flavors of Unix, Windows, DOS, BeOS, and OpenVMS.
