Most people still view an invoice as a document: a PDF file that they can open, read, print, and archive. For accounting software, however, a PDF is generally just a visual representation of data. The system still has to extract the invoice number, dates, supplier, customer, VAT, amounts, and line items before it can automatically…
PL/PDF v5.31 can now generate Tagged PDF documents directly from Oracle PL/SQL. But what is a Tagged PDF? A normal PDF describes where text, images and graphics appear on a page. A Tagged PDF also describes what that content means: headings, paragraphs, lists, tables, figures and their logical reading order. In that sense, PDF tags…
PL/PDF v5.31 introduces native PAdES B-B and PAdES B-T digital signature support directly from Oracle PL/SQL. PAdES — PDF Advanced Electronic Signatures — is the ETSI standard family for advanced electronic signatures embedded in PDF documents. The current baseline specification is defined by ETSI EN 319 142-1 and is part of the European electronic-signature standards…
PL/PDF v5 now supports AES-256 encryption for PDF documents generated directly inside Oracle Database. Why is this important? Oracle permissions protect data while it is inside the database. But once a PDF is downloaded, emailed or stored elsewhere, that protection no longer applies. AES-256 encryption adds protection directly to the PDF file itself, making it…
We have reached an important milestone in PL/PDF: native PDF digital signing in Oracle PL/SQL. The new PLPDF_DIGSIG implementation creates a detached CMS/PKCS#7 signature using SHA-256 and RSA entirely inside Oracle Database—without a Java stored procedure or Bouncy Castle dependency. It is a deliberately simple first version, but an important step toward a fully native…
