Unreal-Engine-Memory-Guard

Unreal-Engine-Memory-Guard is a free and open-source plugin for Unreal Engine aimed at providing enhanced security measures. This plugin introduces a mechanism to guard in-memory values using strong encryption and data integrity verification.

Features

• Secure Data Storage: Uses AES encryption to ensure that in-memory values are stored securely.

• Data Integrity: The signature (hash) of each value ensures that the data remains untampered during its lifecycle in memory.

• Base64 Encoding: Uses Base64 encoding to safely represent encrypted data as a string.

• Template Implementation: Works seamlessly with any trivially copyable datatype.

• Blueprint Integration: Supports a blueprint wrapper, enabling easy use within blueprints. It uses wildcard property values, making it adaptable for different data types.

• Easy Integration: With a familiar UE-style API, integrating and using Memory Guard is a breeze for any developer familiar with Unreal Engine.

• Reliable Decryption: Only returns the decrypted value if the signature matches, ensuring data hasn't been tampered with.

Installation

1. Clone or download the repository.
2. Copy the plugin to your Unreal Engine project's Plugins directory. If you don’t have one, create it.
3. Restart the Unreal Engine Editor.
4. Enable the Unreal-Engine-Memory-Guard plugin via the Plugin Manager.

Usage

• After installation, the FGuardedValue template can be used in your code.

• Initialize the guarded value using the SetValue method, which encrypts and hashes the provided value.

• Retrieve the original data using the GetValue method, which decrypts the data only if its integrity is maintained.

• For Blueprint users, use the provided blueprint wrapper to easily integrate and use the guarded values in your blueprints.

• You can use this struct anywhere in your code where you want to ensure that specific in-memory values remain safe and unaltered.
