Linux timestamp server questions


Hello all!

Do you know where to find some documentation/information/application on how to setup a timestamp server on linux (for digital signing purposes)?

Searching this forum found nothing.
Searching Google found only http://owcapage.wordpress.com/?s=time+stamp but can't put it working and information is few.

Maybe I'me searching with wrong key word (linux timestampt server howto)!

Any help on this?

Thank you and keep the good work!

Tough to say, since you don't say what you're trying to sign, and how you're wanting to sign it.

Unix/Linux timestamps are based on the Unix epoch stamp. and there are lots of routines in lots of languages to spit this out, along with 'human readable' date/time stamps. But without knowing what you're trying to do, and how, we can't help much.

Hello TB0ne!

Thank you.

After some research I think this is a TSA Server. These servers issues a timestamp certificate on POST (or other kind of) request by the client. Is not a single timestamp like this 1271514798. Its a timestamp certificate to use with digital qualified certificate to authenticate documents. This way documents are certificated by identity and time. This way you can know, with legal validity, that the person who signed was, for instance, the president of the company at that exact time.

We developed an application to sign documents but we use some free TSA Servers (since the others are paid and customers must choose and pay them, not us) for demo purposes. The problem is these free servers are very unstable and some times we face problems on prsentations and develop time. This way we want to configure owr own for develop and demo purposes since we are not certificated authority, for sure.

Regards.

Ah, that's different. What specific problems are you facing, with what TSA product? Are you using openTSA? What makes you say it's not stable?

Again, we'll be glad to help, but we have to know WHAT we're trying to help WITH.
