Is there any PDF reader I can use on my Linux machine with digital signature validation support

Diverging from ഗവണ്മെന്റ് ഓഫീസുകളിൽ എങ്ങനെ സ്വതന്ത്ര സോഫ്ട്‍വെയറിന്റെ പ്രചാരം വർധിപ്പിക്കാം.

@joseph.jose was looking for an alternative for Adobe reader.

suggestions were Okular, pdf-shuffler. @raju found LiOS useful in conversion.SMC’s OCR was also mentioned.

as per @raju, the issue with NIC eOffice is the software requires Authentication by Adobe, where new versions of Adobe reader are not supported on Linux.

Discuss pdf stuff here.
