Library that handles locating and fixing vulnerable trivial and nontrivial redactions inside PDF files.
./install.sh should handle making all the dependencies, though you may need to install libraries used by poppler.
aws_trivial_redaction_locate.rb is a script which does a simple first pass of a PDF document using courtlistener's
xray utility to identify whether a document has any black boxes overlaying text, and then uses locate.sh to perform
a more fine-grained analysis to detect trivial redactions.
The nontrivial directory contains scripts outlining how to protect nontrivial redactions.
