John The Ripper (64-bit)

John the Ripper 64-bit is a decrypting and decoding program designed to verify the strength of the user's password and attempt to recover lost passwords using a variety of built-in algorithms. Built from the ground up to deal solely with passwords, this versatile password utility is delivered without a graphical user interface and can only be used through a command window. 

Because the user must learn how to control this tool using just text commands and parameters, John the Ripper will most likely pique the interest of more experienced PC users and technicians who can overlook this disadvantage and focus solely on the real success rate of password recovery. On the other hand, by removing the GUI, the app is now compatible with a wide range of legacy PC settings and can run on ALL versions of the Windows operating system. 

To learn how to use the program to test and recover passwords, users simply need to understand a few command parameters and syntax. The most basic application is to type the whole name of the executable file, then add a few required settings and options before typing the file containing passwords or password recovery hints. 

It employs many ways for password testing and recovery, including the most simple "single crack" method and the more advanced "incremental" and "external" methods, which use the provided word library to filter and faster guess passwords. The software can operate in benchmark mode, which allows any user to test their password strength for a certain period of time. To make long password testing and recovery sessions more manageable, the app's developers integrated a helpful feature for saving and restoring sessions. The software can halt its work and save a printable log with a summary of its completed tasks. 

While John the Ripper is not the most appealing or prominent password-checking and recovery program on the market, it is nonetheless useful for people who merely want simplicity and dependability. However, many more customers may look for solutions with a fully developed interface and additional capabilities. 

You can download and use it for free. The app's premium version, John the Ripper Pro, is available for purchase on its official website.
