timestamp service wanted ( X.509 / TSP )

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&timestamp 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.
