ABOUT ADOBE READER – Advisories, Formatting, and Functionality:
All Invoices digitally signed by Trustweaver are legally signed documents that are in strict
compliance with the applicable VAT laws of each individual country for which they have
been submitted by Dell for digital signatures.
All PDF Invoices digitally signed by Trustweaver utilize Adobe PDF functionality.
TrustWeaver is currently using several accredited Certification Authorities in order to sign
documents in accordance with the local legislations. Adobe Reader is however pre-configured with
very few CA-certificates. This results in Adobe advisories in various portions of the digitally signed
Invoice. These Adobe advisories do not mean the digitally signed e-invoices are not compliant! Legal
compliance is determined by rules issued by public entity administrations. The rules for certificate
recognition in Adobe Reader are driven by business considerations without any impact on legal
compliance. Trustweaver advises that issuers of tax-compliant signing certificates are currently
rarely recognized by Adobe.
Trustweaver advises that it is working with Adobe to resolve the signature validation issues and the
fixes are expected to be deployed in phases by country over a period of time. The reminder of this
document will provide information about these Adobe advisories; explain the possible views that
may be displayed and how to view the validation information. For additional information about the
compliance of electronic signatures on invoices in PDF format provided by Trustweaver, please go to
the following link:

Invoice by changing local computer setting. The information and instructions for changing local

Häufige Fragen und Antworten zu Rechnungen mit „digitaler Signatur”
Frage: Was ist eine digitale Signatur und wozu wird sie benötigt? Antwort: In den meisten Ländern steht “digitale Signatur“ für eine elektronische Unterschrift die einzigartig mit
dem Unterschreibenden verbunden ist, nur von diesem kreiert werden kann, sowie diesen identifiziert. Die digitale Signatur ist mit dem Inhalt des unterzeichneten Dokumentes derart verknüpft, dass Änderungen im Inhalt ersichtlich wären. Die digitale Signatur einer elektronischen Rechnung im PDF Format stellt die Echtheit und Integrität der Rechnung sicher.
Frage: Gibt es eine Möglichkeit, die Echtheit einer digital unterschriebene PDF Rechnung zu überprüfen? Antwort: Für zusätzliche Informationen und um die von der Firma Trustweaver verwendeten digitalen Signaturen
zu bestätigen, benutzen Sie bitten den Link: https://twa.trustweaver.com/tseiod/validate.aspx, insbesondere den Abschnitt: “HOW TO VIEW DIGITAL SIGNATURE VALIDATION & TIME STAMP INFORMATION” (Wie Sie digitale Unterschriften überprüfen & Informationen zum Zeitstempel)
Frage: Beim Öffnen der PDF Rechnung könnten Sie unter Umständen einem Warnhinweis Ihrer Adobe Software
erhalten. Warum wird diese Meldung generiert und was hat sie zu bedeuten?
Antwort: Die digitalen Signaturen, die Trustweaver verwendet, basieren auf digitalen Zertifikaten durch staatlich beaufsichtigte Zertifizierungsstellen. In vielen Ländern gewährleisten diese Zertifikate die gesetzliche Anerkennung. Adobe Reader verwendet Prüfungsroutinen für digitale Signaturen, die auf kommerziellen Schemata basieren und deshalb oftmals nicht die staatlich beaufsichtigten Zertifizierungstellen erkennen.
Frage: Bedeutet die Warnmeldung des Adobe Reader, dass die Signatur auf der PDF Rechnung ungültig ist?
Antwort: Nein. Alle digital unterschriebenen Rechnungen, die von Trustweaver ausgeliefert werden, sind rechtskräftig unterschriebene Dokumente. Die Rechnungen werden unter genauer Einhaltung der gültigen Mehrwertsteuergesetze in den jeweiligen Ländern erstellt.
Frage: Wie kann ich die Adobe Reader Warnhinweise in der Zukunft vermeiden?
Antwort: Die Warnhinweise können mit einer einmaligen Änderung in den lokalen Einstellungen des jeweiligen Computers deaktiviert werden. Diese Änderung ist für jede der nicht erkannten Zertifizierungsstellen
notwendig.Eine Anleitung, wie Sie diese Einstellung ändern, finden Sie im Abschnitt „CHANGING LOCAL
SETTINGS TO PREVENT ADOBE ADVISORIES (LOKALE EINSTELLUNGEN UM ADOBE WARNHINWEISE ZU VERMEIDEN“).

conformità con le leggi IVA applicabili nel paese o nei paesi in cui Dell opera.
Tutte le fatture con firma digitale fornite da Trustweaver utilizzano le funzionalita’ di Adobe PDF.
TrustWeaver attualmente utilizza diverse Autorità di certificazione accreditate, al fine di firmare documenti in
conformità con le legislazioni locali. Adobe Reader è comunque preconfigurato con pochissimi certificati CA. Ciò si
traduce in messaggi di allerta da parte di Adobe in varie parti della fattura con firma digitale. Questi avvisi di
Adobe non si riferiscono alla non compatibilita’ della firma digitale delle fatture elettroniche! La conformità legale
è determinata dalle regole emanate dalle amministrazioni pubbliche del paese di competenza. Le regole per il
riconoscimento del certificato in Adobe Reader sono determinate da considerazioni di mercato, senza alcun
impatto sulla conformità legale. Trustweaver ricorda che attualmente gli enti che rilasciano certificati conformi
alle normative di tassazione sono raramente riconosciuti da Adobe.
Trustweaver ricorda inoltre che sta lavorando alacremente con Adobe per risolvere i problemi relativi alla
convalida delle firme digitali e che e’ impegnata a rilasciare nei vari paesi nuove soluzioni per ovviare al problema.
I futuri messaggi di notifica di Adobe forniranno informazioni relative alle nuove soluzioni: come visualizzare le
certificazioni e le informazioni di convalida. Per ulteriori informazioni sulla conformità delle firme elettroniche
delle fatture in formato PDF offerta da Trustweaver, visitare il seguente link:
