If you are trying to use these tools to decrypt your own files, the "paper" or instructions usually emphasize these steps:
Set Save Format: You must change the g_save_format value in your config.cfg file to 2 (or sometimes 1) so the game saves files in a format the decrypter can handle.
Drag and Drop: Most versions of the tool work by dragging the game.sii file directly onto the SII_Decrypt.exe.
File Growth: A successful decryption will significantly increase the file size (e.g., from ~200KB to ~3MB).
The SII Decrypt tool, often distributed by user Sniper on the SCS Software forums, is a community-standard utility for converting encrypted .sii save files into readable text for editing. Users can modify game values by setting the save format to '2' in config.cfg and dragging the file onto the decryptor, with alternatives including an online decoder and various GitHub-hosted versions.

Before diving into the forums, let's break down the terminology.
.zip or .rar files. Inside every base.scs or def.scs file lies the entire game logic—models, textures, sounds, and definitions.engine.sii (Engine torque/power)camera.sii (Interior camera angles)traffic_data.sii (AI vehicle spawn rates)economy_data.sii (Income, fines, fuel prices)Why decrypt? SCS Software protects their files using a proprietary binary format. When you try to open a raw .sii file from inside a vanilla .scs archive, it looks like gibberish—symbols, dots, and unreadable characters. Decryption (often called "decompiling" by forum users) converts that binary data back into human-readable text so you can edit it.
The search volume for this exact phrase exists for three primary reasons:
game_data.sii. To merge them manually, you must decrypt both to see the raw text.“I spent 3 hours looking for a decryptor – just use SCS Extractor + the XOR script. Most ‘encrypted’ SII files are just XORed with 0x55. Check the Tools subforum sticky.” – Max (SCS Forum user, 2022)
Step 1: Locate the target .sii file inside a .scs mod or base game archive.
Step 2: Use SCS Extractor on the .scs archive → this gives a folder with .sii files in compiled binary format (looks like garbled text if opened in Notepad).
Step 3: Download SII_Decrypt.exe from a trusted link in an SCS Forum modding thread (search: "SII_Decrypt tool by knkenshin").
Step 4: Drag & drop the compiled .sii file onto SII_Decrypt.exe – it generates a new file named [original]_decrypted.sii.
Step 5: Open _decrypted.sii in Notepad++ to see plain text definitions (e.g., SiiNunit header, attributes like price, power, name). sii decrypt scs forum

Decrypting SII files—the specific format used for save data in games like Euro Truck Simulator 2 (ETS2) and American Truck Simulator (ATS)
—is a common task for players looking to edit their profiles, money, or levels. Since these files are often encrypted or saved in binary format, they appear as "gibberish" when opened in standard text editors. Popular SII Decrypting Tools
The SCS Software community has developed several reliable tools to handle these files: trucky/sii-decrypt-ts - NPM
into human-readable plain text, enabling advanced game-save editing
. This utility is often discussed as a vital tool for tasks that the game does not support natively through its standard UI. Core Functionality Binary to Text Conversion: The primary "feature" of SII Decrypt is its ability to take encrypted or binary files (like profile.sii
) and convert them into a text format that can be edited with programs like Automatic Re-encryption:
A key "proper" behavior noted by forum users is that there is no need to manually re-encrypt files after editing; the game engine automatically reads the plain text file and re-saves it in the proper binary format upon the next save. Key Use Cases Discussed on SCS Forums
Forum members use this tool to perform specific "features" or hacks not available in-game: Profile Duplication: Decrypting profile.sii
to change the profile name and then manually renaming the folder to the corresponding Hexadecimal value Garage Management: Downgrading or selling garages by modifying the lines within a decrypted Economy Tweaks:
Quickly editing player money and experience values without using third-party trainer software. Mod Order Recovery:

The SCS Software community, particularly those involved in modding Euro Truck Simulator 2 (ETS2) and American Truck Simulator (ATS), frequently encounters the need to access the game's internal data. If you are searching for "sii decrypt scs forum," you are likely looking for a way to read or edit encrypted game files.
This guide explains what SII decryption is, why the SCS forums are the best resource for it, and how to use the most popular tools safely. 🛠️ What is an SII File? SCS Files: These are the proprietary archive files
SCS Software uses .sii files to store a vast array of game data. These are essentially text files, but they are often distributed in an encrypted or "binary" format to prevent accidental corruption or to keep game balance intact.
Plain Text: Readable in Notepad; usually found in user profiles or simple mods.
Encrypted/Binary: Appears as "gibberish" symbols when opened; requires a decrypter to convert into readable text. 🏛️ Why the SCS Forum is the Gold Standard
When searching for "sii decrypt," the SCS Software Forum is your safest and most reliable source. Modding tools for ETS2/ATS change frequently as the game engine updates. Safety: Community members quickly flag malicious software.
Updates: Authors post "Experimental" versions for new game patches (e.g., 1.50+).
Support: If a file fails to decrypt, the forum users can identify if it’s a "format" error or a "version" mismatch. 🔧 Top Tools Recommended on the Forums
Most forum threads will point you toward one specific, community-vetted tool: SII_Decrypt.exe. 1. SII_Decrypt (by various contributors)
This is a small command-line utility. It doesn’t have a fancy window; it simply processes the file and spits out a readable version.
How to use: Drag your encrypted .sii file and drop it directly onto the SII_Decrypt.exe icon.
Result: The file is overwritten with a readable text version. 2. SiiNunit and Game Save Decrypters
For those trying to edit save games specifically, the forums often recommend "Save Game Decrypters." These are specialized because save files use a slightly different encryption method than general game data files. 📖 Step-by-Step: How to Decrypt Your Files
If you’ve found the correct thread on the SCS forum, follow these steps to edit your files:
Backup Your File: Always copy your game.sii or info.sii to a safe folder before touching it.
Download the Tool: Look for the latest version of "SII Decrypt" in the Modding or Tools section of the SCS Forum. The "Drag and Drop" Method: Open your file explorer. Locate your encrypted .sii file. Drag it over the SII_Decrypt.exe file. A black command window may flash briefly; this is normal.
Edit: Open the .sii file with Notepad++ (Standard Windows Notepad can sometimes break the file formatting).
Save: Once you make changes, simply save. The game can usually read decrypted (plain text) files just as easily as encrypted ones. ⚠️ Common Troubleshooting
"File is already decrypted": If the tool doesn't change anything, try opening the file in Notepad++. If you see SiiNunit {, it’s already readable.
Game Crashes: If the game crashes after you edit a decrypted file, you likely have a syntax error (a missing bracket { or a typo in a value).
DLC Protection: Some paid DLC files are protected differently and may not be decryptable with standard forum tools to prevent piracy. If you'd like, I can help you further. Let me know: Are you trying to edit a save game or a mod file? What specific game version are you running?
Let’s get technical. Based on hundreds of forum posts, the SII encryption isn't military-grade AES. Instead, it uses a proprietary rolling XOR cipher combined with a simple compression step (often LZ4 or a custom variant).
