Time Stamping

TSA Authority

Timestamping is an important mechanism for the long-term preservation of digital signatures, time sealing of data objects to prove when they were received, protecting copyright and intellectual property and for the provision of notarization services. 

  

The TSA Authority (Time Stamping Authority) works as a plugin for most Windows webservers. It means that it is not required to operate an extra TSA machine. 

   

Benefits:
- IETF RFC-3161 compliant
- X.509 standards compliant
- Works with any standards-based Certification Authority
- Uses the local available machine clock, synchronised to a UTC Time Server
- Easy to use through friendly programs like Adobe Acrobat or PDF Signer
- Supports up to 4096 bit RSA keys
- Up to 40 timestamps per second 

   

Requirements:
- Windows operating system with IIS
- Microsoft .NET Framework 2.0 

  

A fully functional version of our TSA Authority is available for testing purposes at this link: http://www.ca-soft.com/request.aspx 

 

Note: The TSA Authority does not require any credentials. 

  

  

 Our Time Stamping Authority is compatibile with Adobe Acrobat products. The PDF Signer product includes timestamping feature so every document digitally signed by PDF Signer can be timestamped automatically using the TSA Authority. 

   

 Long-term validation purposes – Using our software you can sign and timestamp PDF documents for long-term validation purposes. PDF Signer supports advanced digital signatures which include embedded RFC 3161 compliant secure timestamps. Such signatures can be verified even after the signer’s certificate expires or is revoked. 

   

 SHA-2 hash function – Our software may sign PDF documents using SHA-256, SHA-512 hash algorithm and RSA 2048 or higher key length according to ETSI TS 102 176-1 V2.0.0 (“ALGO Paper”). 

  

If you are interested in running your own timestamping service, you may contact us for our RFC 3161 compliant TSA Authority.
