Adobe Acrobat Timestamp Servers

DigiStamp's trusted cloud timestamp service and purchaseable SecureTime Servers support RFC 3161 and other standards, so are compatible not only with our own tools but Adobe Acrobat and others.

 

What is the Adobe® Acrobat Timestamp Server support?       

Here's an example PDF file that you can download to view and verify on your computer with Adobe Reader. (More Samples Here) Summary: The content of this PDF file has been notarized by DigiStamp via an electronic timestamp. This is evidence that this content and your signature existed at a point-in-time. You can view this evidence using Adobe Acrobat on your computer. This file's content cannot be altered without the tampering being detected by the Acrobat Reader software.

Supported Versions: Adobe Acrobat 7 and newer support both digital signatures and trusted timestamping.

 

Value added: Trusted third-party witness to the contents of the document and when you signed the document.  If a digital signature is used, the timestamps adds these protections to the signature (more information is here).

 

Privacy maintained: Timestamping does not send your document over the internet - only a SHA hash of the signature is sent to DigiStamp to create the timestamp (more information is here).  

 

No additional files needed:  The document, digital signature, and trusted timestamp exist together in the single .PDF file.

Get Started

Timestamps start at $.40 ($10 minimum), creating an account is quick and easy. Volume pricing information is available here. Complementary solutions can be explored here, and other tools including our web applications are discussed here.

Adobe provides instructions about how to configure timestamps in Adobe Reader 8 at this link (alternatively, this link). Or, we provide instructions below for versions 9+.
