Cloud Timestamp Service


The cloud service is on-demand creation of e-TimeStamps by the SecureTime system with 99.99% uptime for 10 years.

DigiStamp provides several functions for clients upon the submission of a hash value

  1. Return an e-TimeStamp of your data: RFC 3161 using PKI (Elliptic Curve 256 or RSA 2048-bit keys), and are traceable to 2 audited events.
  2. An e-TimeStamp that is in compliance wiith CFR-11 and eIDAS as a trust service provider.

    Archive Services include:
  3. Submission of the created e-TimeStamp to the Timestamp Archive. Enables future timestamp renewal with upgraded PKI algorithms.
  4. Inclusion in a hash-chain linking process (keyless timestamp) and produce XML Evidence Record (XMLERS): IETF in RFC 6283 “Evidence Records for Long Term Archiving”.
  5. The DigiStamp warranty is:  If a timestamp’s original crypto method is compromised within 7 years of creation then you have free access to DigiStamp's Archived renewals for that timestamp

DigiStamp offers a free GUI tools for creating timestamps and system developers can use the open, standard, interface and API Toolkit to access our Internet-based timestamp servers within their existing software. If you've already built digital signature capabilities into your system -- with in-house software or third-party programs like BouncyCastle or Adobe Acrobat-- you can probably configure your current system to use DigiStamp. Here is a list of software alternatives.

The data that you timestamp can be in any format. Only the data hash value (e.g. SHA512 hash) is transmitted to timestamp servers; your data is never transmitted outside of your environment.

Security and Reliability

Redundant, geographically-separated servers are used to ensure continual access to DigiStamp’s service. You select one of the DigiStamp server locations; however, in the event the selected server is temporarily unavailable, the client software can automatically failover to another server. DigiStamp continually monitors server utilization to ensure availability and response time. See the description of our certified hardware and the audit process; the DigiStamp approach removes all possible human tampering from the process and puts the trust into audited, NIST-certified hardware.
