- understand the levels of digital signatures
There are some security levels about signatures, on whether a timestamp is necessary, on whether the CA should be official your country, about the HW that create the signature... That allow different properties for different usages.
A 'Trust service provider' offers the highest level of certificate. It will typically be rock solid in court.
But it's ultimately still up to a judge to decide if signatures are valid when you go to courts.
If you don't get a signature from the TSP in your country, it doesn't mean it will necessarily be invalid. It's just not pre-aproved, and you will have to establish it yourself.
(Is there some law person on HN to back me up here ? Do you know of any case where this had been a point ?)
- find a company that provides you a digital certificate.
Some IDs in Europe already come with one (especially in Estonia)
