Secure Password Hashing for Unreal Engine Projects

BetterArgon2 provides a complete Blueprint-accessible implementation of the Argon2 password hashing algorithm - winner of the 2015 Password Hashing Competition. Protect user credentials in your games and applications with industry-standard cryptographic security, all accessible directly from Blueprints without writing a single line of C++.

Core Features:

• Simple Password API: Hash and verify passwords with a single Blueprint node using secure default parameters. Perfect for quick implementation of login systems.

• Advanced Parameter Control: Fine-tune security parameters including time cost, memory cost, parallelism, hash length, and salt length for your specific requirements.

• Multiple Algorithm Variants: Support for all three Argon2 variants - Argon2d (data-dependent), Argon2i (data-independent), and Argon2id (hybrid, recommended).

• Raw Bytes Operations: Generate raw hash bytes for key derivation, encryption keys, and other cryptographic operations beyond password hashing.

• Utility Functions: Built-in functions for generating cryptographically secure random salts, hex encoding/decoding, and error handling.

• Encoded Hash Format: Produces standard Argon2 encoded strings containing hash, salt, and parameters - fully compatible with other Argon2 implementations.

Use Cases:

• User authentication systems (login/registration)

• Secure credential storage

• Key derivation for encryption

• Token generation

• Save file password protection

• Multiplayer game account systems

Important Considerations:

• Computational Cost: Argon2 is intentionally slow to resist brute-force attacks. Default parameters use 64MB memory and take ~100-500ms per hash. Avoid calling in the game thread for real-time applications.

• Platform Limitation: Currently Windows only (Win64). Cross-platform support planned for future updates.

• Not for Runtime Encryption: This plugin is for password hashing, not data encryption. Use Unreal's built-in encryption for file/data protection.

Development Transparency:

AI-generated content has been used strictly as a supportive tool during the development phase for purposes including code commenting, ensuring robust pointer usage, and rigorous quality assurance of critical C++ structures.

BetterArgon2 provides a reliable, secure, and convenient approach to password security within Unreal Engine projects.
