Timestamp is defined as a security protocol by international standards which provides legal proof of existence of a digital data at a particular time. Timestamp Client creates timestamp request by getting hash of the file to be timestamped and sends this request to a particular timestamp server. Afterwards it receives timestamp response from the server and stores to local file system after validation and verification processes. For digital data such as a signed agreement, a transaction or an application etc., proof of the existence for a particular time is very crucial for current e-trade and e-government applications. Nevertheless timestamp is required for varying kinds of digital data that need copyright including a new idea, photograph, model, drawing, research, formula or an algorithm.

According to the Turkish Electronic Signature Law published on January 15, 2004, Timestamp refers to a record verified with a secure electronic signature given by an authorized Electronic Certificate Service Providers in order to retain the exact time of creating, altering, sending, receiving or/and storing a digital data.

Timestamp Client Properties

Timestamp Client provides following features:

  • Creates timestamp request by getting hash of the file and sends to the timestamp server.
  • Checks received timestamp response with corresponding file and validate it.
  • Validates timestamp responses taken before.
  • Verifies the certificate of timestamp server by using a policy file.
  • Creates timestamp requests for all kind of files or digital data.
  • Connects to the server by using proxy on request.
  • Users can request the remaining credits.

Solutions

Hash Algorithm Support

Timestamp Client provides the flexibility for timestamp requests to be created by any hash algorithm from SHA-1 and SHA-2 family.

Certificate Verification Support

In addition to validate receiving timestamp responses, timestamp client can verify the certificate of timestamp server.

User Friendly Interface

Timestamp Client comes with a user friendly interface that promotes ease of use.
