This quick tutorial covers how to protect PDF file with password using Python. It presents a complete overview of the process including the system configuration, and step-by-step algorithm, along with a running code sample that demonstrates how using Python PDF password protect feature can be embedded into your applications. It also explains different types of encryptions to protect data in PDF documents.

Steps to Protect PDF File with Password using Python

1. Configure the IDE to use Aspose.PDF for Python via .NET to secure PDF documents
2. Get the source PDF document with the Document class
3. Protect the input PDF file while passing the password string and other arguments for the Encrypt method
4. Write the secured PDF document to the disk or a stream

These steps summarize how using Python password protect PDF feature can be used to keep the data secure in PDF files. You need to load the source document and set the password string while specifying the encryption algorithm. Finally, export the protected document that will need the password while opening the file, as well as while editing and modifying its contents.

Code to Create Password Protected PDF File using Python

To password protect PDF Python code snippet is presented in the above section. It demonstrates the basic use case which you can modify or enhance depending on your needs. For instance, the parameters of the Encrypt() method include the cryptographic algorithm like RC4X128, AESx256, etc. to apply advanced and complicated encryption as per your requirements. Similarly, you can forbid or allow different permissions for the target PDF document.

In this article, we have understood how to create password protected PDF file using Python. Whereas, if you want to learn to decrypt PDF files, refer to the article on How to Decrypt PDF File using Python.
