A fast passcode decrypting utility that was designed to help users test the strength of their passwords or recover lost passphrases

We've just released John the Ripper 1.9.0-jumbo-1, available from the usual place, here. Only the source code tarball (and indeed repository link) is published right now. I expect to add some. John The Ripper is an open source and very efficient password cracker by Open-Wall. It is an Open Source tool and is free, though a premium version also exists. Initially, its primary purpose was to detect weak password configurations in Unix based Operating systems. Today it supports cracking of hundreds of hashes and ciphers.

Mar 29, 2019 John the Ripper is a fast password cracker which is intended to be both elements rich and quick. It combines a few breaking modes in one program and is completely configurable for your specific needs for Offline Password Cracking. John the Ripper Pro is a free and open source password cracker tool for Mac computers.This tutorial will show you how to use John the Ripper to crack Windows 10, 8 and 7 password on. 8 and 7 Password with John the Ripper. John the Ripper is designed to be both feature-rich and fast. It combines several cracking modes in one program and is fully configurable for your particular needs (you can even define a custom cracking mode using the built-in compiler supporting a subset of C).

Creating strong passwords seems like an easy task at first glance, but it may actually take more than one would expect. Since there are many programs specially created to break such locks, it's probably a good idea to actually test the strength of a passcode before using it.

Runs from a command line interface

A tool that is quite useful for this purpose is John the Ripper, a command-line utility that will also show its worth in case you need to recover a lost passkey. Since it doesn't have a GUI of its own, you will have to open a Command window and run it from there to view the parameters which can be used to carry out the process.

The actual usage procedure is quite easy and you will have to follow a simple syntax which starts with the executable of, followed by the desired options and then by the password files.

Multiple methods of recovering passwords

There are several modes in which this application can work, starting with the 'single crack' method, followed by the word list and 'incremental' ones. It is also possible to employ a so-called 'external' mode which acts like a word filter. When using John the Ripper for testing purposes, you can run the benchmarks for a specific time by providing manually the appropriate value.

A great thing about this tool is that you will be able to save sessions and restore them when necessary, using their corresponding parameters. The status of these sessions can even be printed and you also have the possibility to have the deciphered passwords displayed.

To end with

All things considered, John the Ripper could actually be one of the better choices whenever someone needs to recover a password or assess the strength of a new one without having to go through a whole series of configurations. Nonetheless, the lack of a proper interface and of more functions may certainly deter some users from utilizing it.
