Plugin not decrypting PDF with "hardened" DRM (ADE 3.0) #183
Description
First of all I would like to say a Big Thank You! to noDRM and a980e066a01 for enabling the decryption of DRM for ADE 3.0.
I have successfully used this plugin with Calibre Portable Edition 5.44.0. to decrypt PDFs with "hardened" DRM (ADE 3.0).
However today I came across a PDF from the same source which fails to decrypt the PDF when added to Calibre.
