Develop a comprehensive password strength analyzer and custom wordlist generator. The tool should assess the strength of user-provided passwords and facilitate the creation of tailored wordlists for security testing and analysis. The password analyzer should leverage the zxcvbn library or implement custom entropy calculations to evaluate password strength, providing detailed feedback on potential vulnerabilities. The wordlist generator should enable users to input personal information such as names, dates, and pet names, incorporating these elements into the generated wordlists. The generator should also include features to create variations of words, such as leetspeak transformations and the appending of years or other numerical patterns. The tool should support exporting the generated wordlists in a .txt format, making them compatible with common password cracking tools. The user interface can be implemented using either a command-line interface (CLI) or a graphical user interface (GUI) with tkinter. The final deliverable is a functional tool that accurately evaluates password strength and generates customized wordlists optimized for specific attack scenarios.
