  Welcome to Time Stamping Authority (TSA) Service

Time Stamping Authority (TSA)


Technical Summary:

ADSS Server is a J2EE application offering multi-function eTrust services, including digital signing, signature verification, long-term archiving, OCSP certificate validation, Timestamping, certificate issuance, etc.
This web application uses a standard timestamp (RFC3161) request to protect the document. The document’s fingerprint hash is included within the signed timestamp token response.
  System Requirements:

  The following is required to run this demo:
Standard internet browser only
 
Interoperability Testing Service:
You can directly test your Time stamp client applications against the GlobalTrustFinder TSA Service.

The service is located on the following address:
  • URL = http://services.globaltrustfinder.com/adss/tsa
TSA Response Processing:
TSA responses are signed by the GlobalTrustFinder TSA Service using the RSA/SHA1 algorithm. The certificate used to verify the TSA responses has a common name of “GlobalTrustFinder TSA Service” and its full certificate chain is available here.

Your TSA client applications must trust this certificate in order to verify the signature on the TSA responses correctly.
