signatures are not verified nor read

[nic.chierichetti]

Hello,

I currently use Adobe Acrobat DC thanks to my university enterprise plan, but I cannot verify digital signatures with it.

I have read that with the latest versions of this software, the signature verification should be included automatically, but when I open a verified file, all the content after the signature is not displayed, and the sign tab tells me that there isn't any signature.

Of course, I checked with other softwares, and the signature is valid. Already tried to re-install, repair and fix the software.

Can we get some more details, please.

1. You say "all the content after the signature is not displayed". What do you mean, exactly?

2. You say "other software" showed the signature is valid. Can you tell us which software and exactly what you see?

1.  this is what I see if I try to open it with Adobe Acrobat PRO DC

the message says: "The font 'YAYNRD+TimesNewRomanPSMT' contains values /BBox not valid"

but the real problem is that other softwares perfectly read the file and the signature. Adobe doesn't read the signature neither the document

2. other softwares like FirmaOK!, Dike6, P7Sviewer
