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

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.





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.
