DESCRIPTION
This code reads meta information from PDF (Adobe Portable Document Format) files. It supports object streams introduced in PDF-1.5 but only with a limited set of Filter and Predictor algorithms, however all standard encryption methods through PDF-1.7 extension level 3 are supported, including AESV2 (AES-128) and AESV3 (AES-256).
