# Funktionsweise
* Passwortgenerierung: Die Anwendung generiert ein 32-stelliges Passwort mit Großbuchstaben, Kleinbuchstaben und Ziffern (entspricht dem Befehl `apg -a 1 -m 32 -n 1 -M NCL`).
* Zwischenablage: Mit dem Button "In Zwischenablage kopieren" wird das Passwort in die Zwischenablage kopiert.
* Docker: Der Container enthält nur die Go-Anwendung und keine zusätzliche Linux-Distribution.
# Baue die Go-Anwendung
```
go build -o password-generator ./
```
# Baue das Docker-Image
```
docker build -t password-generator .
```
# Starte den Docker Container
```
docker run -p 8080:8080 password-generator
```

<h1>Hilfe: API-Endpunkt</h1>
<p>
Diese Anwendung bietet einen API-Endpunkt, um Passwörter direkt über die Kommandozeile abzurufen.
Der Endpunkt gibt das Passwort im Plain-Text-Format zurück.
</p>
<h2>Endpunkt:</h2>
<p><code>http://localhost:8080/api/password</code></p>
<h2>Beispiele:</h2>
<h3>Mac/Linux (Terminal):</h3>
<pre>curl http://localhost:8080/api/password</pre>
<h3>Windows (PowerShell):</h3>
<pre>Invoke-RestMethod -Uri http://localhost:8080/api/password</pre>
<h3>Windows (cmd):</h3>
