Decrypt Repack - Ix

The command ix decrypt repack is a composite operation. It instructs the system to perform two sequential actions on a specific file or package:

| Tool Name | Purpose | Compatibility | |-----------|---------|----------------| | IX Extract (by Modding Community) | Decrypts basic IX archives | The Witcher 3, early Unity games | | QuickBMS + .ix script | Universal decryption framework | Many game engines | | WolvenKit | Full REDengine suite (handles .ix as .archive) | Cyberpunk 2077, Witcher 3 next-gen | | UnityEX / UABE | For Unity-based .ix containers | Generic Unity games | | Custom Python scripts | AES/XOR decryption + repack | Developer-specific |

Note: WolvenKit has largely replaced manual IX decryption for CDPR games, but standalone IX files still appear in mod bundles. ix decrypt repack

Repacking is the trickiest part. After modifying decrypted files, you must:

Many guides stop at decryption, but Repack is what makes your mod playable again. Without repacking, the game won’t recognize the loose files. The command ix decrypt repack is a composite operation

Repacking requires reversing the decryption process exactly:

Use a repack tool specific to your game. For generic XOR, modify the Python script to reverse the operation. Repacking is the trickiest part

You might use this command in several scenarios:

---

Place the new .ix file in the game’s data directory. Launch the game. If it crashes, you missed a checksum or padding.
