FreeTSA ( Certification Practice Statement

Trusted timestamping is the process of securely keeping track of the creation and modification 
times of a document. Security here means that no one - not even the owner of the document - should
be able to change it once it has been recorded provided that the timestamper's integrity is never 

FreeTSA trusted timestamping Software as a Service (SaaS) provides an easy method to apply RFC 3161
trusted timestamps to time-sensitive transactions through independently verified and auditable date
and UTC (Coordinated Universal Time) sources.

For multiple files, the general concept is that timestamping a single file that contains an aggregate 
list of fingerprints of other files, also proves that these other files must have existed before the 
aggregate file was created, provided that both the aggregate file and the referenced file are available
during verification process. Freetsa also offers the possibility of URLs timestamps (do not abuse). 
If you are interested in implementing timestamps on your project / company using the FreeTSA service, 
you can contact me for specific requirements. Freetsa can also be used within the Tor anonymity network.

Web online Signature: The files are NEVER uploaded to the FreeTSA server, the browser generates a hash 
(TSR) and FreeTSA signs it. FreeTSA respects the user's privacy 100%.

Request Digest: md4 / md5 / rmd160 / sha / sha1 / sha224 / sha256 / sha384 / sha512.
