Architecture & Security

The NewhouseNet Password Generator & Strength Auditor is engineered to produce cryptographically sound, high-entropy credentials and provide comprehensive local evaluation of user credentials against dictionary, pattern, and multi-billion-hash/sec GPU attacks.

🛡️ Real-Time Password Strength Auditor Comprehensive client-side evaluation of custom passwords: instant 0–100 security scoring, character composition breakdown, sequential glyph and keyboard walk detection, and breach wordlist auditing.

🔐 Cryptographically Secure PRNG Powered by window.crypto.getRandomValues() on the client and random_int() on the server, ensuring uniform, non-deterministic distributions free from pseudo-random modulus biases.

🔤 Granular Character Class Inclusions Full control over upper case (A-Z), lower case (a-z), numeric digits (0-9), and special symbols (!@#$%^...), with intelligent filters to exclude visually ambiguous glyphs (1, l, I, 0, O).

📊 Shannon Entropy & Crack Time Modeling Real-time computation of mathematical entropy ($E = L \times \log_2 N$), evaluating strength tiers against offline high-performance GPU clusters ($10^{11}$ hashes/sec), slow KDFs, and rate-limited online logins.

⚡ Diceware Passphrases, PINs & Bulk Export Generates memorable Diceware-style multi-word passphrases with custom delimiters, standard numeric PIN codes, session recall history, and batch provisioning export to CSV and text files.
