Unity Asset Bundle Browser

An enhanced Unity Editor tool for managing and inspecting AssetBundles.

Note: This is an enhanced fork of the original Unity Asset Bundle Browser with additional features.

Features

Configure Tab

Assign assets and scenes to bundles through a visual interface. Similar to using the AssetBundle control at the bottom of the Inspector, but with a dedicated management view.

Build Tab

Build AssetBundles with extended options:

• Build Target - Select target platform
• Bundle Selection - Build all bundles or a single bundle
• File Extension - Append a custom extension to output files (e.g., .bundle)
• XOR Encryption - Simple XOR encryption for basic bundle obfuscation
• Compression - None, LZMA (Standard), or LZ4 (Chunk Based)
• Advanced Options - Exclude type info, force rebuild, strict mode, dry run, etc.
• Copy to StreamingAssets - Automatically copy builds for standalone player use

Inspect Tab

View contents of built AssetBundles:

• Load individual files or entire folders
• Decrypt and inspect XOR-encrypted bundles
• View bundle contents and asset details

XOR Encryption

This fork includes simple XOR encryption for AssetBundles:

Building Encrypted Bundles

1. In the Build tab, enable XOR Encryption
2. Enter your encryption key
3. Click Build

Inspecting Encrypted Bundles

1. In the Inspect tab, enable Decrypt XOR
2. Enter the same key used during build
3. Add and select bundles to inspect

Runtime Decryption

Use AssetBundleXORRuntime class in your game code:

using AssetBundleBrowser;

// Decrypt file on disk before loading
AssetBundleXORRuntime.DecryptFile(bundlePath, "your_key");
var bundle = AssetBundle.LoadFromFile(bundlePath);

// Or decrypt in memory
byte[] encryptedData = File.ReadAllBytes(bundlePath);
byte[] decryptedData = AssetBundleXORRuntime.DecryptData(encryptedData, "your_key");
var bundle = AssetBundle.LoadFromMemory(decryptedData);

Security Note: XOR encryption provides basic obfuscation only. It prevents casual inspection but should not be relied upon for sensitive data.

Editor Menu Tools

Right-click bundle files in Project view:

• Assets > AssetBundles > XOR > Encrypt Bundle(s)
• Assets > AssetBundles > XOR > Decrypt Bundle(s)

Installation

Via Git URL (Recommended)

1. Open Unity Package Manager (Window > Package Manager)
2. Click the + button (top left)
3. Select Add package from git URL...
4. Enter: https://github.com/kienbb/AssetBundles-Browser.git
5. Click Add

Via manifest.json

Add to your Packages/manifest.json:

"com.unity.assetbundlebrowser": "https://github.com/kienbb/AssetBundles-Browser.git"

Usage

After installation, access the tool via Window > AssetBundle Browser.
