iText Core/Community 9.0.0

For this Q4 release, we’re pleased to announce a new major version of iText. iText Core version 9.0 introduces significant new features, support for new specifications, and revised APIs to delight developers.

We’ve added support for the ISO/TS 320003 and 320004 standards, enabling even more secure PDF documents. Also on the list is the finalized digital signature validation module, along with a new API to easily get layers used in a page, and improved PDF/UA signing.

NOTE: Since iText 9.0 is a major release version, it naturally means a break in compatibility with iText 8. As the developers among you will appreciate, this is necessary to make quality-of-life improvements and reduce our technical debt.

However, thanks to the solid foundations laid with iText 7 and 8 there are few major API differences in iText 9. The iText Knowledge Base has extensive documentation on the breaking changes to ease the migration of existing projects from earlier versions.

New ISO Standards Support

First and foremost, iText Core version 9.0 incorporates support for the very latest ISO PDF document security standards. ISO/TS 32003 adds AES-GCM encryption to the PDF 2.0 specification, allowing documents to be protected with high-performance, yet extremely secure encryption.

ISO/TS 32004 introduces an integrity protection mechanism for encrypted PDFs, using a Message Authentication Code (MAC) to ensure authenticity. To fully understand what this means for securing PDF documents, we highly recommend reading two great articles on the PDF Association site: ISO 32004: an overview and the follow-up MACs vs. signatures in PDF which go into detail on this subject.

Digital Signature Validation Module

On the subject of PDF digital signatures, we’re also proud to present the finalized version of our dedicated validation module. This forms an integral piece of iText’s enhanced digital signing capabilities introduced with iText 8.

The aim is to provide simpler, more extensive API methods to not just sign PDF documents, but also validate the digital signatures within them – whether iText created them or not. Since you can validate multiple document revisions as well as certificate chains, iText can now be your Swiss Army knife for digital signatures, as well as PDF creation and manipulation.

This release enables you to only validate a single signature in a document, as opposed to all signatures. In addition, the signature validator will now work for encrypted documents.

API Improvements

There are also major refinements to iText’s API. These include streamlining PDF/A and PDF/UA creation and conformance to simplify the process. We’ve also developed a new API to identify the layers used in a page. This will help to find which Optional Content Groups (OCGs) belong to which page in a document.

Signing of PDF/UA documents has been improved. When creating a signature form field iText will now take into account if an alternative description is set in the accessibility properties of the signature appearance. Additionally, if you forget to set a font for the signature appearance this will now result in a conformance exception, rather than a property error.

Further improvements have been made to the rebuilding of invalid cross-reference (xref) tables in corrupt documents. When iText encounters and resolves such errors in non-strict mode, specific information on the cause will now be provided.

Adding to the recent addition of RSASSA-PSS encryption support for .NET, this release now allows it to be supported in FIPS mode.

Along with that is improved font selection and general handling, performance enhancements, and much more. iText has a reputation amongst Java and .NET developers for its speed and ease of use, and we’re ensuring that remains the case in the future.

Make sure to check out the Breaking Changes if you’re migrating from a previous version of iText.

Pull Requests

Once again, we’d like to thank Matthias Valvekens for another pull request submission. This relates to Unicode, and adds support for platform 0 encoding 3 in the Truetype and OpenType character map table. This is used in some fonts shipped with macOS, among other places.

Bug Fixes and Miscellaneous

For content extraction, we fixed a bug in the RegexBasedLocationExtractionStrategy API (Java/.NET) . It now produces better results by default when processing multiple pages.

We fixed an edge-case bug in Certificate Revocation List validation. When a CRL response existed, but its issuer was neither trusted, nor self-signed, it could result in a stack overflow error.

In addition, a fix was made to SVG rendering to honor dy attributes in parent text attributes.
