Random Password Generator

The Random Password Generator creates strong credentials by allowing precise control over length and character sets. It targets IT admins, developers, security teams, and individuals who must comply with password policies, rotation schedules, and breach risk reduction. Users specify whether to include uppercase, lowercase, digits, and symbols, and can opt to exclude ambiguous characters. The output is a single password string along with metadata such as length and entropy estimate.
Core generation logic uses a cryptographically secure RNG to select characters from the chosen set. Entropy is estimated as length times log2(charset_size), providing a numeric gauge of strength. The tool supports optional passphrase-like workflows as advanced features, but standard use focuses on random passwords. It also records the charset configuration in the output to help downstream auditing and policy validation.
Inputs are validated to prevent insecure configurations: minimum length, at least one character set must be enabled, and exclusions must not remove all available characters. If a cryptographic RNG is unavailable, the tool gracefully reports an error and avoids generating a password. Outputs include the password, its length, the active character set, and a strength score to aid decision-making.
Localization follows common security standards; units are characters; no currency or region-specific data is used. The tool adheres to best practices for credential generation and can be integrated into automation pipelines for onboarding, rotations, or API keys. Unique value lies in explicit entropy calculation, configurable exclusions to reduce ambiguity, and a simple, auditable output suitable for governance.
