Password Generator

The tool generates passwords by drawing from user-selected character pools. You specify length and which sets to include (lowercase, uppercase, digits, symbols). Validation ensures at least one set is active and length stays within defined bounds.
It uses a cryptographically secure RNG to select characters from the active pool and, optionally, a seed for reproducible results in controlled environments. Ambiguous characters can be excluded to reduce confusion when writing passwords by hand.
An entropy estimate (bits) is returned based on pool size and length, enabling quick security assessment. Outputs include the password and optional metadata suitable for auditing or integration with password management workflows. If seed input is provided, the generator can reproduce the same password for repeatable deployments; otherwise, it relies on system cryptographic RNG for randomness. The advanced mode supports custom symbol sets and seed-based generation to meet compliance requirements, while the basic mode emphasizes speed and simplicity. The tool is designed for developers, IT admins, security-conscious individuals, and small teams needing policy-compliant credentials without network access or storage of passwords. It differentiates itself through granular pool control, ambiguity reduction, immediate entropy feedback, and reproducibility options. It can be integrated into onboarding, credential rotation, and documentation workflows, with outputs suitable for audit trails and automated tooling.
