DVS Clipster + DCI/DCP

[Andrew McCarrick]

I'm a little confused by this and was wondering if anybody could clear this up...

In this PDF file, http://www.visionaryforces.com/downloads/DVS-Clipster-3G-DCI-Mastering-User-Guide.pdf, on page 4 - 4 (Page after the Section 4.1.3 heading), where it says:

"Use the button on the right-hand side of the field Private Signing Key
to select the private key file (*.pfx) that should be used to sign the extra
files of the DCP (Signing Key). For this you may have to enter a password to authenticate your usage of the private key. Afterwards the corresponding public key is detailed in the field Public Key above. This public key will be attached to the extra files and has to be used by D-Cinema players to verify the origin of
the files of a DCP."

What is this referring to by "Private Signing Key"

[Wolfgang Woehl]

It refers to the concept of a digital signature, used for example with email and other things where you want to ensure the authenticity of a file (has nothing to do with /encryption/ of the file, mind you). Same goes for a DCP's CPLs and PKLs. Your "signature" has a public and a private part and in order to sign anything you need to access its private part.

So is this something I can just make up, or is it something that needs to be assigned to me by some organization?

[Wolfgang Woehl]

You create your own keys and the safety of the related private key-parts is crucial. You don't want anyone to create keys for you and you don't want copies of your private key-parts floating about (apart from your personal "safe" infrastructure). And you do want to circulate the /public/ key-parts (which can be "signed", by the way, with your digital signature, to ensure their authenticity).

See http://www.gnupg.org/ for primers and apps.

Alright, could I possible get a tutorial on the actual process of creating these keys? Cause I'm not following 100%. How's it done (the process), what software, ect. and how do I get this into the .pfx extension DVS Clipster is asking for.

I've never dealt with any form of encryption keys before...

[Wolfgang Woehl]

You really need to understand the basic concepts, no way around reading some introductory material. A search for pfx+private signing key will quite likely give you a long enough list.

Okay, I found a way to make a .p12 file (which is supposedly the samething as a .pfx file?), so can I use that in DVS Clipster?
