Portable Password Generator

The Portable Password Generator solves the need for strong credentials when network access is restricted or machines are offline. It is designed for security professionals, IT admins, developers, and travelers who require reliable, locally generated passwords. It accepts user-defined length and character-set options, and can enforce basic password policy constraints without sending data externally.
Conceptually it builds a random pool from chosen character classes (uppercase, lowercase, digits, symbols) and draws characters uniformly to create a password of the requested length. Optional exclusions remove ambiguous characters such as I, l, O, 0. An entropy estimate is computed from pool size and length to help assess strength.
Offline operation and portability are core value propositions. The tool does not transmit or store inputs or outputs, enabling secure credential generation on air-gapped systems. It supports multiple usage scenarios, including quick one-off passwords, policy-compliant sequences, and integration into secure workflows where installation of third-party software is undesirable.
Key features include multi-field inputs for length and character-set, advanced options for entropy and policy checks, deterministic output support via seeding if provided, and a clean textual password output suitable for copy-paste into password managers. Distinguishing factors are its freeware license, portability, offline behavior, and explicit focus on password quality without marketing embellishments.
