strong_password 1.1.0

A Dart/Flutter package that generates very strong passwords the way Gmail does, plus per-service deterministic passwords, passphrases, PINs, and password strength estimation.

1.1.0

• Added DeterministicPasswordGenerator — derive a unique strong password per service from a single master secret using HMAC-SHA256 from the Dart-team crypto package. Nothing is stored; the same input reproduces the same password.
• Added GeneratedPassword (password + options bundle) and StrongPasswordGenerator.generateMany(count, unique:) for bulk/unique output.
• Added PasswordProfiles with curated standard / high / paranoid / pin configs.
• Added crack-time estimation: PasswordStrength.crackSeconds() and PasswordStrength.crackTimeLabel().

1.0.0

• Initial release.
• StrongPasswordGenerator — Gmail-style strong random passwords with guaranteed character groups, configurable length, ambiguous-character removal, and custom alphabets.
• PassphraseGenerator — memorable multi-word passphrases.
• PinGenerator — numeric PINs.
• estimatePasswordStrength — entropy-based strength estimator with common weak-password detection.
• Cryptographically secure randomness via Random.secure(). Zero dependencies.
