Hi folks,
I have some technical documents on .pdf format download from Internet. They are allowed to download by filling personal information. I supposed they have been encrypted.
Each time I have to re-filling in the same personal data before I can read the document. It is not convenient. Besides their contents can't be copied/pasted. Each time trying to highlight their text warning popup saying this operation not permitted.
I succeeded printing them as .ps files. However still I could not copy/paste their content. Running
# ps2pdf tmp_001.ps tmp_001.pdf
Code:
This PostScript file was created from an encrypted PDF file.
Redistilling encrypted PDF is not permitted.

GNU Ghostscript 7.07: Unrecoverable error, exit code 1
I can open the .ps file with GIMP but could not re-save it as .pdf becuase .pdf format is not available on GIMP for saving.
Kindly advise is there a way to decrypt the .pdf file not having to filling same personal data to read it.
TIA
