**Zone**: Yellow · **Software development and IT**

## The situation

You take over someone else's code. It is hard to read. The code contains company names, addresses and credentials.

## How it works

1. You paste the code.
2. **The Schleuse replaces secrets.** Names, addresses, identifiers and credentials are replaced with stand-in words. This happens on your side, not in the cloud. Amounts and dates stay as they are.
3. **The AI answers, the Schleuse translates back.** The answer contains the stand-in words. On your side they turn back into the real names.

## Example

**Your question to the AI:** Explain what this code does. Suggest improvements.

**What is in your text:**

> # fetch invoices for **Müller Landtechnik GmbH**
> url = "https://**api.mueller-landtechnik.intern**/v1"
> token = "**tk-live-81d9f0aa27**"

**What the cloud AI sees:**

> # fetch invoices for **Company Alpha**
> url = "https://**Server_A**/v1"
> token = "**Token_A**"

*This example is made up.*

## What you get

You get an explanation and suggestions.

## Good to know

Credentials do not belong in code. The Schleuse protects them, but it does not replace proper storage.

## Zone of this use case: Yellow

Only through the Schleuse. And only to targets you have approved.

## Status of the Schleuse

Version 0.1 Alpha. So far tested only with made-up examples. Not reviewed by third parties. No legal advice.
