secure_db 1.0.6

A unified secure database package that provides encrypted storage using both Hive and SQLite with automatic encryption/decryption.

1.0.6

• SECURITY FIX: Fixed critical security vulnerability in fallback key generation
  • Replaced weak Random(hashCode) implementation with PBKDF2-like key derivation using 100,000 SHA-256 iterations
  • Fallback keys are now cryptographically strong and resistant to brute-force attacks
  • Added warning logging when secure storage is unavailable and fallback mode activates
• Enhanced Security: Improved password-based key derivation (deriveKey method)
  • Increased default iterations from 10,000 to 100,000 for stronger key derivation
  • Added configurable iterations parameter for flexibility
  • Better documentation on security properties
• Testing: Added comprehensive test suite for encryption service
  • 26 new tests covering encryption, key generation, security properties, and edge cases
  • Regression tests to prevent future security vulnerabilities
• No Breaking Changes: Drop-in security improvement with full backward compatibility

1.0.5

• Dependency Updates: Updated to latest compatible versions for better pub.dev scoring
  • Updated flutter_secure_storage from ^9.0.0 to ^10.0.0
  • Updated crypto from ^3.0.3 to ^3.0.7
  • Updated sqflite_common_ffi from ^2.3.6 to ^2.4.0
  • Updated flutter_lints from ^3.0.0 to ^6.0.0
• Bug Fixes: Removed deprecated encryptedSharedPreferences parameter for Android (data automatically migrated)
• Compatibility: Improved compatibility with latest Flutter SDK and dependencies

1.0.4

• Improved API: Enhanced API consistency with new instance-based access patterns.
• Dual Access Support: Added better support for both factory methods (SecureDB.hive()) and direct instance access (SecureHive.instance).
