Bug ID: 435260
Summary: Strange checking for signing bounds
Product: okular
Version: 20.12.3
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general

signed PDF
SUMMARY
As far as I can see in the code, only byteRange.last() and byteRange.first()
are used.
That's strange because of:
$ pdfsig ul-1172651010388-20210402102439.pdf
Internal Error (0): couldn't find default Firefox Folder
Digital Signature Info of: ul-1172651010388-20210402102439.pdf
[...]
- Signed Ranges: [0 - 23225], [31227 - 167454]
Signed Ranges becomes in pairs. Thus, when getting signed data, okular will
treat the whole PDF file to be signed, which is not the case.
I'm preparing a patch now, which will get this issue solved.
