ICryptFactory:
- `IRSADecryptor this[string key]`-Indexer für den Zugriff auf Entschlüssler per Schlüssel hinzugefügt.
- Methode `TryGetRSADecryptor` für das sichere Abrufen von Entschlüsslern eingeführt.

CryptFactory:
- `IRSADecryptor`-Indexer für die Verwaltung von Entschlüsslern implementiert.
- Ein `Decryptors`-Dictionary hinzugefügt, um RSA-Entschlüssler nach Schlüssel zu speichern.
- Konstruktor aktualisiert, um `Decryptors` mit einem bereitgestellten oder leeren Dictionary zu initialisieren.
- `TryGetRSADecryptor` zur Entschlüssler-Abfrage implementiert.
