Get Security Info

This guide will show you how to get information about locked or password-protected PDF documents. The program returns whether or not a PDF is encrypted and the encryption method used.

Before you begin #

You should get your API key from your UniCloud account.

If this is your first time using UniPDF SDK, follow this guide to set up a local development environment.

Project setup #

Clone the project repository #

In your terminal, clone examples repository. It contains the Go code we will be using for this guide.

git clone https://github.com/unidoc/unipdf-examples.git

Navigate to the security folder in the unipdf-examples directory.

cd unipdf-examples/security

Configure environment variables #

Replace the UNIDOC_LICENSE_API_KEY with your API credentials from your UniCloud account.

Linux/Mac #

export UNIDOC_LICENSE_API_KEY=PUT_YOUR_API_KEY_HERE

Windows #

set UNIDOC_LICENSE_API_KEY=PUT_YOUR_API_KEY_HERE

How it works #

Lines 9-15 import the UniPDF packages and other required dependencies.

Lines 17-24 authenticate your request with your UNIDOC_LICENSE_API_KEY with the init function.

The main function in lines 26-39 validates your input and passes it as an argument to the printSecurityInfo function.

Lines 41-80 define the printSecurityInfofunction, which accepts inputPath as a parameter. The function checks if the input PDF is encrypted or not and the encryption method.

Run the code #

Run this command to get security info about locked PDFs. This will also get all the required dependencies to run the program.

Sample output #

You will get the locked PDF’s encryption status on the terminal.
