Re: How to sign a Document, that can be validated with a WebBrowser?

[Stefan Thom]

Vadim,

how to specify something else then a key to be packed into the pkcs7 file? Besides does pkcs7 really sign the content? I can not specify a signing key with it?!? Isn't pkcs12 what you meant? But how to specify a non key kontent here?

Do you have an idea?

Hi there,

has anybody an idea how to sign a binary Document, like a word Document, 
that if it is downloaded from a Web Server the signature is validated. 
Like with signed jar archives they are validated before they are executed.
    

Good point with jar. Signature test is part of flow control so it is
verified.
  

Do you have any experience with that?

Any signature verification is built-in into Word?

I just checked that. Nope, just VBscripts can be signed not the document itself. I'm looking anyways for a Document independent way because tomorrow it can be a PDF or whatever.

Ok, now one could think another file format with binary document
being there inside. PKCS7 Signed could be fine.

Does a complete document fit in there? I think I've got to play with that a little.Do you have any experience with that?

would if fit your project?

I'll try that. Thxx
Stefan

hope this helps,
Vadim
