+Summary: Byte ordering problem on SerialNumber when creating x509 certificate
+
+Description of Problem:
+There's a problem with the X509CertificateBuilder class
+
+Steps to reproduce the problem:
+1. try this test case:
+using System;
+using System.IO;
+using Mono.Security.Authenticode;
+using Mono.Security;
+using Mono.Security.X509.Extensions;
+using Mono.Security.Cryptography;
+using System.Security.Cryptography;
+using System.Security.Cryptography.X509Certificates;
+
+namespace CertifBug
+{
+	class MainClass
+	{
+		public static void Main(string[] args)
+		{
+			Mono.Security.X509.X509CertificateBuilder cb = new
+Mono.Security.X509.X509CertificateBuilder (3);
+			Guid serial=Guid.NewGuid();
+			string serialnumber=serial.ToString();
+			cb.SerialNumber=serial.ToByteArray();
+			Console.WriteLine("sn : "+BitConverter.ToString(serial.ToByteArray()));
+			cb.IssuerName="CN=pipo";
+			cb.NotBefore=DateTime.Now;
+			cb.NotAfter=DateTime.MaxValue;
+			cb.SubjectName = "CN=pipo";
+			cb.SubjectPublicKey=RSA.Create();
+			ExtendedKeyUsageExtension eku = new ExtendedKeyUsageExtension();
+			eku.KeyPurpose.Add("1.3.6.1.5.5.7.3.2");
+			cb.Extensions.Add(eku);
+			cb.Hash = "SHA1";
+			byte[] rawcert=cb.Sign(RSA.Create());
+			//FileStream fs=new FileStream("./pipo.crt",FileMode.OpenOrCreate);
+			//fs.Write(rawcert,0,rawcert.Length);
+			//fs.Close();
+
+			X509Certificate cert=new X509Certificate(rawcert);
+			Console.WriteLine("sn : "+BitConverter.ToString(cert.GetSerialNumber()));
+			}
+		
+	}
+}
+2. 
+3. 
+
+Actual Results:
+
+sn : 18-C6-1D-07-78-CA-F0-44-AB-B2-5C-73-EB-79-0C-60
+sn : 60-0C-79-EB-73-5C-B2-AB-44-F0-CA-78-07-1D-C6-18
+
+
+Expected Results:
+sn : 18-C6-1D-07-78-CA-F0-44-AB-B2-5C-73-EB-79-0C-60
+sn : 18-C6-1D-07-78-CA-F0-44-AB-B2-5C-73-EB-79-0C-60
+
+How often does this happen? 
+always
