Cannot get info about encrypted file #123
Comments
When encrypting a PDF, there is a choice as to whether also encrypt metadata or not. If metadata is encrypted, too, then you must decrypt before you can access anything.

Betreff: [pmaupin/pdfrw] Cannot get info about encrypted file (#123)
I tried to get pdf info from file given as attachment STM32HitexRefManual.pdf<https://github.com/pmaupin/pdfrw/files/1594407/STM32HitexRefManual.pdf>
Here is info returned :

Info is encrypted, from pdfrw doc, I read :
The examples directory has a few scripts which use the library. Note that if these examples do not work with your PDF, you should try to use pdftk to uncompress and/or unencrypt them first.
Would it be possible to handle encrypted files as pdfinfo does?
