Quick Start: Determining encryption type using the web service API

The following C# code example determines the type of encryption that is protecting a PDF document named EncryptLoan.pdf.

using System;

using System.Collections;

using System.ComponentModel;

using System.Data;

using System.IO ;

namespace GetEncryptionType

{

	class Class1

	{

		[STAThread]

		static void Main(string[] args)

		{

			try

			{

				//Create an EncryptionServiceService client object

				EncryptionServiceService encryptionClient = new EncryptionServiceService(); 

				encryptionClient.Credentials = new System.Net.NetworkCredential("administrator", "password");

				//Create a BLOB object to store the PDF document 

				BLOB inDoc = new BLOB();

				//Specify the PDF document 

				string path = "C:\\Adobe\\EncryptLoan.pdf";

				FileStream fs = new FileStream(path, FileMode.Open);

				//Get the length of the file stream 

				int len = (int)fs.Length; 

				byte[] ByteArray=new byte[len];

				//Populate the byte array with the contents of the FileStream object

				fs.Read(ByteArray, 0, len);

				inDoc.binaryData = ByteArray; 

				//Determine the encryption type

				EncryptionTypeResult encryptTypeResult = encryptionClient.getPDFEncryption(inDoc);

				if (encryptTypeResult.encryptionType == EncryptionType.PASSWORD)

					Console.WriteLine("The PDF document is protected with password-based encryption");

				else if (encryptTypeResult.encryptionType == EncryptionType.POLICY_SERVER)	

					Console.WriteLine("The PDF document is protected with policy");

				else if (encryptTypeResult.encryptionType == EncryptionType.CERTIFICATE)	

					Console.WriteLine("The PDF document is protected with certificate-based encryption");

				else if (encryptTypeResult.encryptionType == EncryptionType.OTHER)	

					Console.WriteLine("The PDF document is protected with another type of encryption");	

				else if (encryptTypeResult.encryptionType == EncryptionType.NONE)	

					Console.WriteLine("The PDF document is not protected.");	

			}

			catch (Exception ee)

			{

				Console.WriteLine(ee.Message);  

			}

		}

	}

}
