Quick Answer: What are the Security & OCR Nodes?

[!NOTE] The Security and OCR Nodes are specialized tools for handling document access and text extraction. the Protect/Unlock nodes allow you to add or remove password-based encryption, while the OCR Node uses Optical Character Recognition to turn scanned images or PDFs into editable, searchable text.

Core Capabilities

1. High-Performance OCR

Turn "flat" images (JPG, PNG) or scanned PDFs into fully searchable documents. The OCR node adds an invisible text layer behind the original image, allowing you to highlight and copy text while maintaining the visual original.

2. Enterprise Protection

Automatically apply passwords to every document generated in your workflow. Ideal for sensitive financial reports or private legal filings being sent via the Email Node.

3. Integrated Unlocking

If your workflow needs to process incoming encrypted files, use the Unlock Node as the first processing step to decrypt the stream before passing it to PDF Toolbox.

Configuration Guide

Operation	Setting	Impact
OCR	Language	Select the primary language for higher character accuracy.
Protect	User Password	The password required to open the PDF.
Unlock	Password	The existing password needed to decrypt the file.
Sign	Digital ID	Attach a cryptographic signature for non-repudiation.

Best Practices

DPI Matters: For OCR, ensure your source images are at least 300 DPI for optimal accuracy.
Permission Bitmask: (Advanced) Use the Protect node to restrict specific actions like "Printing" or "Copying" while allowing "Viewing".
