Docotic.Pdf 7.0 with support for digital signatures


We have published Docotic.Pdf 7.0 on our site and on NuGet.

The main feature of this release is support for digital signatures. The library can sign new and existing PDF documents. To sign a document please use one of the PdfDocument.SignAndSave() methods. You can create signatures of different types, in different formats, using different digest algorithms. For complete set of properties please take a look at the new PdfSigningOptions type.

The library can also verify existing digital signatures. It can verify if digest (hash) is valid, check if a signature contains embedded OCSP or CRL revocation data, or if the signing certificate is revoked. You can also access signing and issuer certificate properties. All this is available via PdfSignature.Contents property.

We created Digital signatures group of samples for all new abilities.

Starting from version 7.0 the library no longer uses System.Drawing.Bitmap when drawing images. This and other improvements increase stability of all ASP.NET applications that perform PDF to image conversion. Also, the library now consumes less memory when drawing PDF documents.

This release also contains bug fixes for text and images extraction, drawing of documents, and for processing of forms and annotations.
