    We rarely sell timestamp servers because there are two key advantages to using the cloud-based service: cost and ease of access. In a few cases, in-house timestamp servers may be preferred. More details here.

    Desktop tools for individual signers include web-based applications and third party tools like Adobe Acrobat, MS Office, and others
  • api_toolkit.jpg
    Use the API toolkit to access the trusted timestamp service with your internal systems, such as work flow and data collection. DigiStamp's integration toolkits historically were the primary method of adding timestamps to your existing business applications. Due to wide acceptance of timestamping standards, this function is supported in software like BouncyCastle. DigiStamp's API toolkit is free for our customers. More details available here.

    The Proxy allows many employees and internal systems to securely share access to DigiStamp's trusted timestamp service. Individual workstations access timestamp servers using a customized URL like and require no authentication or special software. The Proxy could even be reconfigured later to use an on-site timestamp server or a different timestamp vendor, and there would be no impact to existing users.
