PDF Service → Decrypt Document

AI-generated

Overview

This node operation decrypts an encrypted PDF document using a provided password. It supports input PDFs either from a public URL or as base64 encoded content. The decrypted PDF can be returned in various output formats including base64 JSON, binary file data, or a download URL. This operation is useful for workflows that need to access or process secured PDF files by removing password protection.

Use Case Examples

  1. Decrypt a PDF document from a public URL by providing the URL and the decryption password, then receive the decrypted PDF as a base64 string in JSON format.
  2. Decrypt a base64 encoded PDF content by supplying the base64 string and password, and get the decrypted PDF as a downloadable binary file.
  3. Use the decrypted PDF URL output to provide a link for downloading the decrypted document.

Properties

Name Meaning
PDF Source Specifies the source of the PDF document to decrypt, either from a public URL or from base64 encoded content.
PDF URL The public URL to the encrypted PDF document to decrypt. Required if PDF Source is 'From URL'.
PDF Base64 The base64 encoded content of the encrypted PDF document to decrypt. Required if PDF Source is 'From Base64'.
Output Format The format in which the decrypted PDF document is returned: as a base64 string in JSON, as a binary file for download, or as a URL in JSON.
Password The password used to decrypt the encrypted PDF document.

Output

Binary

If the output format is set to 'File (Binary)', the node outputs the decrypted PDF as binary data suitable for download or further binary processing.

JSON

  • success - Indicates whether the decryption operation was successful.
  • operation - The operation performed, which is 'decrypt' in this case.
  • format - The output format of the decrypted PDF (base64, file, or url).
  • filename - The filename of the decrypted PDF when output as a file.
  • fileSize - The size of the decrypted PDF file in bytes.
  • base64 - The base64 encoded string of the decrypted PDF when output format is base64.
  • url - The download URL of the decrypted PDF when output format is URL.

Dependencies

  • Requires an API key credential for the PDF Generator API service to authenticate requests.

Troubleshooting

  • Ensure the provided password is correct; an incorrect password will cause decryption to fail.
  • If using 'From URL' as the PDF source, verify that the URL is publicly accessible and points to a valid encrypted PDF.
  • If using 'From Base64', ensure the base64 string is correctly encoded and represents a valid encrypted PDF document.
  • Check the output format setting to match the expected usage (e.g., base64 for JSON workflows, file for binary downloads).
  • Common error messages include invalid JSON input for base64 content, unsupported operation for the resource, or authentication errors due to missing or invalid API credentials.
