Automated PDF Password Protection and Upload to Google Drive

This n8n workflow automates the process of downloading a PDF, adding password protection, and uploading it to Google Drive. Triggered manually, the workflow begins with a manual test trigger that initiates the PDF processing sequence. It downloads a sample PDF file from a public URL, then uploads the PDF to an API service that adds password protection with a specified password (‘mypassword’). Once the file is encrypted, it saves the result as ‘document.pdf’ on disk. Finally, the workflow uploads the protected PDF to a designated folder in Google Drive. This automation is useful for securely managing documents without manual intervention, especially when handling sensitive files that require password protection before sharing or storage.
