Password Generator Plus

Password Generator Plus provides cryptographically secure password creation with user-controlled constraints for individuals and organizations. It targets security-conscious engineers, IT admins, and developers who must meet corporate or policy requirements for account credentials. Use cases include onboarding new users, credential resets, multi-account provisioning, and security audits. The tool outputs plain text passwords suitable for paste into credential managers, secure notes, or password fields while avoiding common re-use.

Conceptually, it builds passwords by selecting random characters from user-defined sets using a cryptographically secure PRNG. Constraints include length, inclusion of uppercase, lowercase, digits, and symbols, plus an exclusion set to remove ambiguous characters. An optional passphrase mode combines a user-provided phrase with a salt-like process to yield high-entropy strings. The algorithm computes per-character entropy as log2(charset_size) and total entropy as length times that value, guiding strength adequacy.

Core features include adjustable length (8–128 by default); toggleable character sets; character exclusions; single or batch generation; and an output format optimized for pasting into password managers. Advanced options allow deterministic seeding for reproducible test scenarios and a basic strength estimate to help policy alignment. The tool is suitable for onboarding workflows, service accounts, and any situation requiring unique, non-predictable credentials.

Edge cases and policy considerations are handled explicitly: invalid length values are rejected; selecting no character sets yields no output; excluding all available characters results in an error; very long requests are bounded. The approach is designed for offline use, supports enterprise and personal use, and emphasizes reproducibility, auditability, and security best practices.
