CryptographicException: Bad Length while sending SOAP request through WSE3.0

We are creating a .net web service client for java based web service.

We are using UsernameForCertificateAssertion turnkey assertion.

Here is the code for my .net client.

using System;
using System.Collections.Generic;
using System.Text;
using Microsoft.Web.Services3;
using Microsoft.Web.Services3.Addressing;
using Microsoft.Web.Services3.Messaging;
using Microsoft.Web.Services3.Security.X509;
using System.IO;
using System.Xml.Serialization;
using FintNamespace;
using Microsoft.Web.Services3.Design;
using Microsoft.Web.Services3.Security.Tokens;
using System.Security.Cryptography.X509Certificates;
using Microsoft.Web.Services3.Security;
using Microsoft.Web.Services3.Security.Cryptography;

namespace PeopleSoftServiceClient
{
    class PeopleSoftServiceClient
    {
        public const string DistinguishedName = "CN=AP Root CA, DC=corp, DC=asc, DC=com";



        [MTAThread]
        static void Main(string[] args)
        {
            Run();
        }

        private static void Run()
        {
            string path = System.Configuration.ConfigurationSettings.AppSettings["Path"];
            string filePath = System.Configuration.ConfigurationSettings.AppSettings["XmlPath"];
            string url = System.Configuration.ConfigurationSettings.AppSettings["URL"];
            string certPath = System.Configuration.ConfigurationSettings.AppSettings["CertPath"];

            try
            {
                PeopleSoftClient client = new PeopleSoftClient(new Uri(url));

                Type type = typeof(FintNamespace.paymentOrigination);

                XmlSerializer serializer = new XmlSerializer(type, "http://www.a.com/messages/fint");


                UsernameForCertificateAssertion assertions = new UsernameForCertificateAssertion();
                UsernameTokenProvider provider = new UsernameTokenProvider("Bob", "Bobby");

                assertions.ServiceActor = "http://schemas.xmlsoap.org/soap/actor/next";
                assertions.X509TokenProvider = new X509TokenProvider(StoreLocation.CurrentUser, StoreName.Root, DistinguishedName, X509FindType.FindByIssuerDistinguishedName);
                assertions.UsernameTokenProvider = provider;


                Policy policy = new Policy(new PolicyAssertion[] { assertions });

                paymentOrigination origination = (paymentOrigination)serializer.Deserialize(new FileStream(filePath, FileMode.Open));

                Console.WriteLine("Sending Request to AP...");

                client.SetPolicy(policy);
                client.SendPaymentOrigination(origination);

                Console.WriteLine("Request Successfully sent...");
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.ToString());
            }
            finally { }

            Console.ReadLine();
        }
    }
}

Code for PeopleSoftClient Class: -

using System;
using System.Collections.Generic;
using System.Text;
using Microsoft.Web.Services3.Messaging;
using FintNamespace;

namespace PeopleSoftServiceClient
{
    [SoapService("https://111.222.011.221:9442/PSIGW/PeopleSoftServiceListeningConnector")]
    public class PeopleSoftClient : SoapClient
    {
        public PeopleSoftClient(Uri to) : base(to) { }

        [SoapMethod("https://111.222.011.221:9442/PSIGW/PeopleSoftServiceListeningConnector?Operation=PaymentOrigination.v1&From=Z_CSS")]
        public void SendPaymentOrigination(paymentOrigination paymentOrigination)
        {
            base.SendRequestResponse("PaymentOrigination.v1", paymentOrigination).GetBodyObject(typeof(paymentOrigination),
                SoapServiceAttribute.TargetNamespace);
        }
    }
}

After executing the above console application, we get a CryptographicException: Bad Length.

System.Security.Cryptography.CryptographicException: Bad Length.

Please let me know how to resolve this issue.
