JD-GUI vs Wordlists: Which Browser Extension tool is Best in 2025?

JD-GUI is an open-source, standalone graphical Java decompiler, available on Kali Linux at /usr/bin/jd-gui, designed for reverse-engineering compiled Java applications by extracting readable source code from .class or .jar files. Developed by Emmanuel Dupuy and packaged for Kali by Sophie Brun, JD-GUI provides a user-friendly GUI to browse class hierarchies, view decompiled Java code, and save sources as .java files. Ideal for cybersecurity researchers, Android developers, and ethical hackers, it supports malware analysis, code auditing, and vulnerability research. Often paired with tools like Dex2Jar, JD-GUI simplifies Java bytecode analysis.

Wordlists is an essential package in Kali Linux (version 2023.2.0), crafted for cybersecurity professionals and penetration testers. This pre-compiled wordlist collection for brute-force attacks includes the renowned rockyou.txt with 14.3 million passwords, making it a leading password-cracking resource for ethical hacking. With a 50.90 MB footprint and support for tools like John the Ripper, Wordlists streamlines security testing, helping identify weak credentials efficiently.
