Passphrase Generator

This tool generates high-entropy passphrases following the XKCD style, combining words from a language-appropriate wordlist with optional digits and symbols. It targets security-minded users who prefer memorable credentials over long random strings. Use in account creation, password vaults, and automation tasks that require strong authentication.
Conceptually, it samples words uniformly from a sanitized wordlist, optionally capitalizes them, and joins them with a chosen separator. If enabled, digits and symbols are inserted within the password at controlled counts. The algorithm estimates entropy from the word count and the inclusion of digits/symbols, and enforces a minimum length when configured.
Audience and differentiators: IT admins needing reproducible passwords for migrations, developers integrating credential provisioning, and individuals who balk at purely random strings. Differentiators include language-aware wordlists, offline operation, reproducible seeds, and explicit configuration for separators and capitalization that preserve memorability.
Core features include: (1) required inputs such as word_count and separator, (2) optional inputs such as include_digits, digit_count_min/max, include_symbols, symbol_set, capitalize_words, min_length, language, (3) outputs the final password and its length, (4) robust validation for input ranges and language support, and (5) error handling for missing data or unsupported language.
