You can perform the manual process described below using REGEDIT. Setup: Registry entries to tell MS Office to retrieve a timestamp But, by observing the verify process in detailed system logs, Office does verify the signatures and timestamps specifically, as described in the introduction related to when your signing certificate expires. Microsoft has not provided a way for us to examine the details or export the signature or timestamp. These values also confirm that there is a timestamp: XAdES-C XAdES-X XAdES-X-L
It should say as shown above in the blue circle “XAdES-T” to confirm the signature is timestamped. In Office navigate the menu option, , you navigate under the “File” tab to “View Signature” then right click on the signature for “Signature Details. How do I know the signature was timestamped? This is done as shown in the graphic below, navigate the menu option, , How do I timestamp a signature? The timestamp is created when you protect the Office document with your digital signature. You need a CA to issue your signing certificate described here. Please do an Internet search for "Add or remove a digital signature in Office files" and look for links to Editor's details: we would give you direct links, but the Microsoft support site is designed to prevent that. Microsoft is your best source of "how to" on this subject. It is a little complex, for example you need to get personal, digital-signing credentials.

Update your DigiStamp account to allow "IP-based Authentication".Update Registry entries to tell Microsoft Office to retrieve a timestamp.There is a one-time setup of Microsoft Office to enable timestamping, described below. A receipt is the receiving party’s timestamped signature of the document you sent, which is strong evidence that they had receipt of the document at the specified time. When your signed documents are sent to a trading partner, ask for an immediate receipt. Once informed, the credit card company can identify inappropriate charges. This process can be compared to calling a credit card company to inform them when your credit card was lost or stolen. It is important in this process to notify the Certificate Authority that the key was compromised. If you timestamp all your signatures, then those signatures created after the compromise can be distinguished. It is important that you can distinguish the documents that you signed with your private key from those that were signed after the key was compromised. There is risk that your private key will be stolen or compromised. Second is that the process to create a digital signature involves using your secret, private, signing key. As a general practice, to maintain the veracity of digital signatures you accept, they should be timestamped to avoid the other party from later stating that their private key was revealed and therefore, any of their signatures with that key might be a forgery. Because DigiStamp countersigns the data files, those signatures created before the private key was compromised are still valid. This would not compromise all data files you ever signed with that key if you also timestamped those previous signatures.
If your private key were to be revealed, then others could sign data files as yourself. In the event your PKI private key is compromised It is like signing a document before a notary - the notary can testify that you appeared before them on a given day to sign a document. These are two basic ingredients to properly execute e-commerce transactions and other business agreements.
A timestamp of that digital signature provides when the digital file was signed. Why would you want to timestamp your signature?Īttest to "when" a digital file was signedĪ digital signature provides who signed the digital file.
