Hello
I already reported a bug when converting from mhtml to Word doc or rtf, that transparent background pngs were rendered with black bg, can’t find my topic but seems related to this:
Kindly advise from which documents can be retrieved? Doc/Docx or Pdf or S/MIME Mhtml etc?
And is it safe? I remember in .net framework it was strongly advised to store certificates in X509Certificate2 and certificate collections in X509Certificate2Collection, also much easier to work with and DISPOSE
@australian.dev.nerds, WORDSNET-25420 adds the ability to extract digital signatures as a byte array from DOC, OOXML, and ODT documents. Here is the original request.
Please refer to our documentation for more details about digital signatures:
oh sorry the request was for Java, OK in .net is there a certificate export option to X509Certificate2 or X509Certificate?
Or the only option is this byte array?
And what about PDF signatures? Can be saved as X509Certificate2 / X509Certificate ?

Just curious as I know nothing about those document structures.
If I understood right, Cert Holder is a collection, means that a single document can have multiple signatures?
If so, any reason to choose a collection/array/etc rather than X509Certificate2Collection for the super sensitive certificates?
Any hope for the addition of X509Certificate2Collection if not a replacement?

Aspose.Words code is ported to Java/C++/Python. The portability is the main reason for CertHolder because X509Certificate2Collection is specific for .NET.
Could you please provide a scenario where X509Certificate2Collection is preferred over CertHolder? I will open a ticket for such a scenario.
Hello,
Thanks, X509Certificate2Collection is specific designed holder of X509Certificate2 collections which will simplify certificate related operations.
Anyway, XPS files can contain digital signatures (certificates) too, hopefully there’s some way to save the certificates from XPS files? If not, possible to add a feature request?
And certificate extraction of PDF files, is something already on the feature request list?

Aspose.Words has limited support for PDF files, and the certicate extraction is not supported. Aspose.PDF already has some support signature extraction. Could you check whether Aspose.PDF functionality suits your needs?
Hello,
Although my choice is Aspose Total (cause it’s cheaper than btoh Email and Words and will have all) but due to the large size of each dll and distribution limitations, kindly note this, specially Aspose PDF dll which is large.
Including Aspose PDF dll only for PDF certificate extraction is not wise, and also not possible for me due to over size limits.
If this feature does not need a lot of huge shared code base from PDF assembly, it will be easy to copy some source code from PDF to Words to add this feature to Words?
I will be willing to pay some extra fee for this feature, or if you have a feature survey poll to ask others’ comments?
@australian.dev.nerds Aspose.Words and Aspose.PDF are completely different products and does not have common code, except licensing code. So there is no easy way to extract part of one product and include it into another one. I am afraid, the PDF certificate extraction is out of Aspose.Words scope and will not be likely to be implemented in Aspose.Words in the foreseeable future.
