About this tool
Analyzes the PDF's encryption dictionary (`pikepdf` / `QPDF`) to report whether a User Open Password is required, the exact cipher revision (`AES-256 R=6`, `AES-128 R=4`, `RC4`), all 8 permission flags (`print`, `extract`, `modify`, `forms`, `annotate`), and clearly warns when a file only has advisory Owner Password viewer restrictions rather than cryptographic access protection.
