Looking for "PDF Public-Key Digital Signature and Encryption Specification"

Feb 13, 2009 1:29 AM

Hi,

i am looking for the following ("old") document:

PDF Public-Key Digital Signature and Encryption Specification

Originally i could be found here:
http://partners.adobe.com/asn/developer/acrosdk/DOCS/ppk_pdfspec.pdf

But not anymore. Does somebody of you still have it? Adobe today just offers the latest documents but i specifically need that older version.
Or is there an archive i don't know of?

Thanks for your help,
ToM

    You can read the PDF 1.5 specification OR even ISO 32000-1 itself for that information. Each feature is "tagged" with the specific version in which it was introduced.

    Digital Signatures were first introduced in Acrobat 4 (PDF 1.3) and have seen various improvements which each version since.

    ToM,

    If you do not try to protect copyrighted materials you loose the ability
    to do so.
