## 1. Executive Summary & Verifiable Zero-Knowledge Architecture

**The Pass Key** (`https://thepasske.com/`) provides four free, zero-telemetry browser utilities for generating and auditing authentication credentials:
1. **Password Generator (`https://thepasske.com/password-generator/`):** Generates 4 to 64 character cryptographically random passwords using uppercase (`A–Z`), lowercase (`a–z`), digits (`0–9`), and printable ASCII symbols (`32 symbols`, total pool `N = 94`). Includes an ambiguity filter that strips `O`, `0`, `I`, `l`, and `1`.
2. **Passphrase Generator (`https://thepasske.com/passphrase-generator/`):** Generates 3 to 10 word random Diceware-style passphrases (`12.925 bits` per word from a 7,776-word list) with customizable separators (`-`, space, `.`, `_`), capitalization, and appended random digits.
3. **PIN Generator (`https://thepasske.com/pin-generator/`):** Generates unbiased 4 to 16 digit numeric PINs (`3.322 bits` per digit) with an optional filter to prevent repeated adjacent digits.
4. **Password Strength Checker (`https://thepasske.com/password-strength-checker/`):** Evaluates password length, character-pool diversity, and predictable pattern weaknesses 100% locally in JavaScript without sending keystrokes over the network.

### Why `window.crypto.getRandomValues()` Matters vs. `Math.random()`
Standard JavaScript `Math.random()` uses a non-cryptographic PRNG (XorShift128+) whose internal state can be reconstructed from observed outputs. The Pass Key exclusively calls `window.crypto.getRandomValues(new Uint32Array(length))`, which draws entropy directly from the operating system's hardware-seeded CSPRNG (`/dev/urandom` on Linux/macOS/Android, `BCryptGenRandom` on Windows, and the Secure Enclave on iOS/macOS).

Users and auditors can verify zero network transmission by opening browser Developer Tools (`F12` -> Network tab), switching to Airplane Mode, and generating or checking passwords (`0 bytes` transmitted).

## 2. Cryptographic Entropy Formula & Multi-Algorithm Crack-Time Benchmarks (2026)

Information-theoretic keyspace entropy ($H$) is calculated in bits as:
$$H = L \times \log_2(N)$$
where $L$ is the credential length and $N$ is the character pool size (`26` lowercase, `52` mixed-case letters, `62` alphanumeric, `94` full printable ASCII, `7,776` EFF Diceware words, or `10` numeric digits).

### Table 2.1: Random Password Entropy & Offline GPU Crack Times (MD5 vs. SHA-256 vs. bcrypt vs. Argon2id)
