Description

Assume you get a 300+MB large pdf and need to know

1) the file names of embedded files if any

2) whether it is encrypted (symmetric or asymmetric)

3) certification level (and whether it is signed)

This should not use more than 5 MB (extra) memory

 

P.S.: seems to an exampe of https://pdfbox.apache.org/ideas.html  "Handle large PDF files"
