Usage

Node Parameters

• Binary Property: Name of the binary property containing the input PDF (default: "data")
• Password: Password to encrypt the PDF file (required)
• Output Filename: Name for the encrypted output PDF file (default: "encrypted.pdf")

Example Workflow

example-workflow.json provides a sample workflow with these steps:

1. When clicking 'Test workflow' → manual trigger
2. HTTP Request - Download PDF → fetch sample PDF
3. PDF Encrypt → apply the password
4. Read/Write Files from Disk → save encrypted_document.pdf

Import it in n8n via Workflows → Import from File, pick the JSON, and run.

The example downloads a sample PDF, encrypts it with your password, and saves it to ~/.n8n-files/encrypted_document.pdf (change the path if your files directory differs).

n8n 2.0 restricts file writes to ~/.n8n-files (see n8n v2.0 breaking changes).
