peepdf
peepdf is a Python tool that analyzes PDF files to find out if the file is harmful or not. The goal of peepdf is to equip all the required components that a penetration tester needs in a PDF analysis. peepdf helps us to see all the objects in the document and shows the suspicious elements. It also supports the most commonly used filters and encodings. It can also parse different versions of a PDF file, object streams, and encrypted files. It also helps to create, modify, and obfuscate PDF files.
