This tutorial demonstrates how PDF Python developers can remove a password from a PDF document by calling the Aspose.PDF Cloud REST API, using the official Python SDK to upload the encrypted file, perform the decryption, and download the unlocked result. For more information about the PDF format, see the PDF file info page.
Prerequisite
- Create an account and obtain API credentials to work with the PDF API
- Download the Aspose.PDF Cloud SDK for Python
- Set up a Python project and install the SDK (e.g.,
pip install aspose-pdf-cloud)
Steps for Removing Password from PDF Document using Python Low Code API
- Import the required classes and modules from the SDK.
- Instantiate a PdfApi object with your client ID and client secret.
- Open the encrypted PDF file and load it into a memory stream.
- Encode the PDF password as a Base64 string.
- Call the PutDecryptDocument method, passing the file name, storage location, and the Base64‑encoded password.
- Use the DownloadFile method to retrieve the decrypted PDF from cloud storage.
The sequence above outlines the complete flow for decrypt PDF document using Python‑based API: create the PdfApi instance, read the source file into a stream, prepare the password, invoke PutDecryptDocument, and finally download the unlocked file.
Code for Removing Password from PDF Online using Python REST Interface
The snippet decrypts a PDF on the cloud. When PutDecryptDocument() is executed, you specify the output file name that will be stored in the cloud; the subsequent DownloadFile call fetches this decrypted PDF.
