Warning on protected PDFs, Meta Information can't be extracted

[bmn]

Hi,

I'm using ExifTool 11.44 Windows Standalone version.

I get the following warning on protected PDFs:
Warning: Install Digest::MD5 to process encrypted PDF - <<filename.pdf>>

The PDFs aren't read protected, but have some restrictions set.
The command line is: exiftool.exe -charset filename=latin "<<filename.pdf>>" -Producer

How can I get the Meta Information of this files, too?

That is odd.  Digest::MD5 should be included in the stand-alone version.  I'll have to look into this.

I just searched the Internet for an example file:
https://tcpdf.org/examples/example_016/

The PDF on this page raises the warning, for example.
I can confirm, that there's the file inc\lib\Digest\MD5.pm in my temp folder.

Very strange.  I downloaded that PDF and I can't reproduce your error.

Maybe try deleting the exiftool temp files and trying again?

Hi,

thank you for the help. After deleting the temporary files, all is working like expected.

Sorry for the inconveniences I should have tried this myself.
