Quick Start: Certifying a PDF document using the web service API

The following code example certifies a PDF document that is based on a PDF file named Loan.pdf. The alias that is specified for the security credential is TonyB and revocation checking is not performed.

using System;

using System.Collections;

using System.ComponentModel;

using System.Data;

using System.IO ; 

namespace SignDocument

{

	class Class1

	{

		[STAThread]

		static void Main(string[] args)

		{

			try

			{

				//Create a SignatureServiceService client object

				SignatureServiceService  signClient = new SignatureServiceService(); 

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

				//Create a BLOB to store a PDF document to sign

				BLOB inDoc = new BLOB();

				//Specify a PDF document to sign

				string path = "C:\\Adobe\\Loan.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; 

				//Specify the name of the signature field

				string fieldName = "SignatureField1[0]";

				//Create a Credential object

				Credential myCred = new Credential(); 

				myCred.alias="tonyb"; 

				//Specify the reason to sign the document

				string reason = "The document was reviewed";

				//Specify the location of the signer

				string location  = "New York HQ"; 

				//Specify contact information

				string contactInfo = "Tony Blue";

				//Create a PDFSignatureAppearanceOptions object 

				//and show date information

				PDFSignatureAppearanceOptionSpec appear = new PDFSignatureAppearanceOptionSpec();

				appear.showDate = true;

				//Specify a legalAttestation value

				string msg = "Any change to this document will invalidate the certificate";	

				//Certify the PDF document

				BLOB signedDoc = signClient.certify(

					inDoc,

					fieldName,

					myCred,

					HashAlgorithm.SHA1,

					true,

					reason,location,

					contactInfo,

					MDPPermissions.NoChanges,

					true,

					msg,

					appear,

					false,

					false,

					false,

					false,

					null,

					null,

					null);

				//Populate a byte array with a BLOB data

				byte[] outByteArray=signedDoc.binaryData; 

				//Save the signed PDF document

				string fileName ="C:\\Adobe\\Loan55.pdf" ; 

				FileStream fs2 = new FileStream(fileName, FileMode.OpenOrCreate);

				//Create a BinaryWriter object

				BinaryWriter w = new BinaryWriter(fs2);

				w.Write(outByteArray);

				w.Close();

				fs2.Close();

			}

			catch (Exception ee)

			{

				Console.WriteLine(ee.Message);  

			}

		}

	}
