Examples

You can set the user password either when you encrypt a file or later with changeupw.

Change the user password of a document that already has one:

pdfcpu encrypt -upw upw enc.pdf
writing enc.pdf ...

pdfcpu changeupw enc.pdf upw upwNew
writing enc.pdf ...


Set the user password of a document that has none. Any encrypted PDF file has either one of the two passwords set. Whenever you change the user password of a document that has a owner password set, you have to provide the current owner password:

pdfcpu encrypt -opw opw enc.pdf
writing enc.pdf ...

pdfcpu changeupw enc.pdf "" upwNew
Please provide the owner password with -opw

pdfcpu changeupw -opw opw enc.pdf "" upwNew
writing enc.pdf ...
