pdftk in.pdf cat 1-endsouth output out.pdf

Ref:- - where I found the above solution.

store a pdf without password

tags | remove password pdf

qpdf --password=YOURPASSWORD --decrypt input.pdf output.pdf

If the password has some special characters, quote it.

qpdf --password="YOURPASSWORD" --decrypt input.pdf output.pdf
pdftk secured.pdf input_pw YOURPASSWORD output unsecured.pdf

Note:- If possible switch to using qpdf instead of pdftk. There were couple of instances where the pdftk command failed and qpdf succeeded.

Ref:- - Mentions qpdf; gives more alternatives.

encrypt a pdf with password

pdftk in.pdf output out.pdf user_pw foo


Note:- I was unable to encrypt a pdf file using Adobe Reader X1 Version 11.0.13 . I could not find the “Tools pane” described in I also tried File → Properties → Security after opening the file. However all the options in that window are greyed out. So I can't add a password from there as well. I was told that Adobe Standard can do this but it costs money whereas pdftk is free. In the end, using pdftk was a no brainer.
