Top Flutter Cryptography, Security and Permissions packages

Last updated: May 18, 2026

Cryptography, security, and permissions are critical components for protecting user data, securing API communications, and adhering to OS-level privacy constraints.

Best Practices for Security

  • Never "Roll Your Own" Crypto: Always use established, community-vetted cryptography packages for hashing, encryption, and JWT decoding. Custom implementations are prone to vulnerabilities.
  • Secure Storage: Never store sensitive keys, API tokens, or user credentials in plain text SharedPreferences. Use platform-secured storage like Keychain (iOS) and KeyStore (Android).
  • Graceful Permission Handling: When requesting permissions (camera, location, contacts), always check the current status first. If a user permanently denies a permission, guide them to the OS settings page gracefully using a package like permission_handler.

The complete list of Cryptography, Encryption, Security, JWT, RSA, and OS Permissions packages is provided below.
