11opt.AddOutput(new FileDataSource("path_to_encrypted_pdf"));
12
13// Perform the encryption process
14plugin.Process(opt);

How to Decrypt a PDF Document

To decrypt a PDF document, follow these steps:

  1. Create an instance of the Security class.
  2. Create an instance of DecryptionOptions with the necessary password.
  3. Add the encrypted PDF file using the AddInput method.
  4. Set the output file path using AddOutput.
  5. Execute the decryption using the Process method.
​
 1// Instantiate the Security plugin
 2var plugin = new Security();
 3
 4// Configure the decryption options
 5var opt = new DecryptionOptions("user_password");
 6
 7// Add input encrypted PDF file
 8opt.AddInput(new FileDataSource("path_to_encrypted_pdf"));
 9
10// Specify the output decrypted PDF file
11opt.AddOutput(new FileDataSource("path_to_decrypted_pdf"));
12
13// Perform the decryption process
14plugin.Process(opt);

Setting Permissions on PDF Documents

When encrypting a PDF, you can set various permissions to control how the document can be used.
