timestamp service wanted
i want to add to my documents a timestamp.
with the [url removed, login to view] Time-Stamp Protocol (TSP).
for this i need a commandline exe that :
- calculate the hash of my file,
- send it to the timestamp server and
- write a textfile with the encrypted hash×tamp to a new textfile.
also i need a commandline&gui application that can check if the timestamp is valid.
i am shure many solutions for this exist.
i will give 50$ to the one that tell me the service provider that have the exe tools i need
and have to lowest costs per timestamp. (i need approx 2000 timestamps / day)
of corse it must be a trusted service that is allwowed to make timestamps for european union.
