  Software setup
You will need to install the DigiStamp software to verify the authenticity of a digital signature or time stamp. There is no charge for using the software to perform a verify actions.

You can install the software here: Install and run. The account setup is not required if you are using the software just to verify a signature or time stamp..
  Preview and import

In the case where someone has e-mailed to you an attachment that contains the signed files, then you will need to save these attachments to your computer. In many email packages you, can "right click" on the attachment as choose "save"; this will copy the attachments from inside the email to a file(s) on your computer. Then, you can start the DigiStamp software and use the "Import" tab to select and then display these files. Here is a screen shot of how to view the signatures and time stamps:

In the example below, the file that contains the time stamps, signatures, and the original documents is a "ZIP" file named "SendToAgency.zip"



The software matches the signatures (files of type ".P7S") with their associated signed documents. The signatures are verified and then displayed in a "Preview" screen.

A common use for our software is allowing multiple people signing the same document - like you would do with a contract agreement this printed on paper. If you have been asked to add your signature to a document, then you can use the preview screen described above. The preview screen has a button "Add signature" that will allow you to create your signature. Then, use the "save" button to write the signature to a file on your computer, ready to be returned by email.

Import button The software will initially present the signature and time stamps to you in a preview mode. In the preview display, you can see the results of verifying each item. But, the files and their signatures/time stamp will be lost when you close the software. You can choose to "import" any of the items that are in the preview and this will save them for reference later. The signed and time stamp documents will be saved on your computer (after clicking import, the software will ask where to save the original documents).

Press the help button in the upper right of the window for additional information. for more details.
