John the Ripper vs Sleuth Kit: Which Kali Linux Tools tool is Best in 2025?

John the Ripper is a premier open-source password cracker pre-installed in Kali Linux (version 1.9.0), tailored for security administrators and penetration testers. This password-cracking tool for cybersecurity audits targets weak credentials using wordlists, brute-force, and rule-based attacks, making it a leading password security testing tool for ethical hacking. With a 77.63 MB footprint and support for hashes like SHA512crypt and MD5, John empowers users to strengthen system security through efficient password audits.

The Sleuth Kit (TSK) is an open-source collection of command-line digital forensics tools, pre-installed on Kali Linux at /usr/bin/, designed for analyzing disk images and file systems to recover evidence in cyber investigations. Developed by Brian Carrier, TSK supports file systems like NTFS, FAT, EXT2/3/4, UFS, and HFS+, enabling forensic analysts, incident responders, and ethical hackers to examine deleted files, partition structures, and timelines. Often paired with Autopsy’s GUI, TSK’s modular utilities provide granular control for advanced forensic tasks.
