About the Utility Tools Suite
Everyday digital tasks—from generating mathematically strong passphrases and evaluating password resistance against GPU brute-force attacks to extracting email addresses from large HTML source files and decoding QR codes from photos—require tools that are fast, accessible, and uncompromising on privacy.
The TU Web Tools Utility Suite combines security best practices (such as the NIST SP 800-63B password guidelines and the zxcvbn entropy model) with client-side zero-knowledge architecture. You can generate random passwords, test password complexity, extract URLs, and decode QR code camera streams with total confidence that zero data leaves your local device.
Cryptographic Passwords
Generate high-entropy passwords and passphrases using browser cryptographic randomness.
Pattern-Based Strength Testing
Detect dictionary words, repeated patterns, and l33tspeak substitutions in real time.
In-Browser Data Extraction
Filter, deduplicate, and extract emails, URLs, and QR code contents entirely client-side.
