Possible Command-Line Interface for timestamping
This is only a copy of what my pdc (prevalent digest client) already does, but the PT client will surely work in a very similar way:
jan@janlap:~$ pdc help Prevalent Digest Creator 1.1 - License: GNU General Public License Command: gui mode: java -jar pdc.jar command line: java -jar pdc.jar -action [send | verify] [options] Options: -f File (required) -d Document Name -e EMail -h Homepage -p Person -pn Project Name -u URL -t Document-Type (1 = Source-Code, 2 = Object-Code, 3 = Text)
Only Filename is required, the other options are optional.
As you can see, this allows an easy and scriptable way to create new timestamps as well as to verify if a file is timestamped already.
Just had the idea that we could also write a little Mozilla Thunderbird
extension, that attachs a little signature to your mails, which contains
one randomly selected of the many hash-values for the latest PTB
-- publictimestamp.org/ptb/ptb-123 ripemd-160 BB774C09AD51E4D7E860DC3A70BBC961E980FA69
This way, we would have tons of evidence for the timestamp-date, which are also very very accurate. Especially when sending to mailinglists :)
This could also be a little client.
Right click on any link to a file in the web, select 'check for Public Timestamp', and the extension searches the PT and checks if this was timestamped (and when).
It's just an easy way for quick verification :)
