List Permissions

The PDF specification defines a set of permissions that may be set for encrypted documents. This command prints the current permission set. Have a look at some examples.

Usage

pdfcpu permissions list [-v(erbose)|vv] [-q(uiet)] [-upw userpw] [-opw ownerpw] inFile


Flags

name description required
verbose turn on logging no
vv verbose logging no
quiet quiet mode no
upw user password no
opw owner password no


Arguments

name description required
inFile PDF input file yes


Examples

pdfcpu does not require any password for listing the permissions of an encrypted document unless the user password is set:

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

pdfcpu perm list enc.pdf
permission bits:            0
Bit  3: false (print(rev2), print quality(rev>=3))
Bit  4: false (modify other than controlled by bits 6,9,11)
Bit  5: false (extract(rev2), extract other than controlled by bit 10(rev>=3))
Bit  6: false (add or modify annotations)
Bit  9: false (fill in form fields(rev>=3)
Bit 10: false (extract(rev>=3))
Bit 11: false (modify(rev>=3))
Bit 12: false (print high-level(rev>=3))


If both passwords are set, you need to provide either one to list permissions:

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

pdfcpu perm list enc.pdf
Please provide the correct password

pdfcpu perm list -upw upw enc.pdf
permission bits:            0
Bit  3: false (print(rev2), print quality(rev>=3))
Bit  4: false (modify other than controlled by bits 6,9,11)
Bit  5: false (extract(rev2), extract other than controlled by bit 10(rev>=3))
Bit  6: false (add or modify annotations)
Bit  9: false (fill in form fields(rev>=3)
Bit 10: false (extract(rev>=3))
Bit 11: false (modify(rev>=3))
Bit 12: false (print high-level(rev>=3))

pdfcpu perm list -opw opw enc.pdf
permission bits:            0
Bit  3: false (print(rev2), print quality(rev>=3))
Bit  4: false (modify other than controlled by bits 6,9,11)
Bit  5: false (extract(rev2), extract other than controlled by bit 10(rev>=3))
Bit  6: false (add or modify annotations)
Bit  9: false (fill in form fields(rev>=3)
Bit 10: false (extract(rev>=3))
Bit 11: false (modify(rev>=3))
Bit 12: false (print high-level(rev>=3))


If only the user password is set then that’s also what you need to provide:

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

pdfcpu perm list enc.pdf
Please provide the correct password

pdfcpu perm list -upw upw enc.pdf
permission bits:            0
Bit  3: false (print(rev2), print quality(rev>=3))
Bit  4: false (modify other than controlled by bits 6,9,11)
Bit  5: false (extract(rev2), extract other than controlled by bit 10(rev>=3))
Bit  6: false (add or modify annotations)
Bit  9: false (fill in form fields(rev>=3)
Bit 10: false (extract(rev>=3))
Bit 11: false (modify(rev>=3))
Bit 12: false (print high-level(rev>=3))
