Validating digitaly signed PDF Spire.Pdf C#

So I am developing a web app that generates a PDF contract from a partial view, and then validates the digital signiture. I came accross an example here . The problem is that an exception is thrown when validating the signiture and for the life of me I cant figure out why...
Here is the code :
public async Task<ActionResult> Upload(HttpPostedFileBase FileUpload)
{
ActionResult retVal = View();
AspNetUser user = DbCtx.AspNetUsers.Find(User.Identity.GetUserId());
bool signitureIsValid = false;
string blobUrl = string.Empty;
if (FileUpload != null && FileUpload.ContentLength > 0)
{
string fileName = Guid.NewGuid().ToString() + RemoveAllSpaces(FileUpload.FileName);
string filePath = Path.Combine(System.Web.Hosting.HostingEnvironment.MapPath("~/Content/pdfs"), fileName);
FileUpload.SaveAs(filePath);
List<PdfSignature> signatures = new List<PdfSignature>();
using (var doc = new PdfDocument(filePath))
{
var form = (PdfFormWidget) doc.Form;
int count = 0;
try
{
count = form.FieldsWidget.Count;
}
catch
{
count = 0;
}
for (int i = 0; i < count; ++i)
{
var field = form.FieldsWidget[i] as PdfSignatureFieldWidget;
if (field != null && field.Signature != null)
{
PdfSignature signature = field.Signature;
signatures.Add(signature);
}
}
}
PdfSignature signatureOne = signatures[0];
try
{
signitureIsValid = signatureOne.VerifySignature(); // HERE SHE BLOWS !
if (signitureIsValid)
{
blobPactUrl = await BlobUtil.BasicStorageBlockBlobOperationsAsync(System.IO.File.ReadAllBytes(filePath));
if (!string.IsNullOrEmpty(blobPactUrl))
{
ApplicantInfo info = DbCtx.ApplicantInfoes.FirstOrDefault(x => x.UserId == user.Id);
info.URL = blobUrl;
info.SignatureIsValid = true;
info.ActivationDate = DateTime.Now;
info.ActiveUntill = DateTime.Now.AddYears(1);
DbCtx.Entry(info).State = System.Data.Entity.EntityState.Modified;
DbCtx.SaveChanges();
retVal = RedirectToAction("Publications");
}
}
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
}
finally
{
System.IO.File.Delete(filePath);
}
}
return retVal;
}
Here is an image of
what it looks like when I'm debuging:
I have checked the signiture and it is valid and cerified... I know I'm missing something basic here... Please help me internet!

Just noticed that I posted this. . . Turns out that the problem was due to bug in the package itself. Upon asking the lovely people at E-Iceblue, the bug was recreated, solved and a new version of Spire.PDF was up on nuget within a week.
great job E-Iceblue, it worked fine :)

equavalant of [DllImport("wininet.dll")] for INTERNET_COOKIE_HTTPONLY in android

I am looking for the equavalant of this DLL in android to handle INTERNET_COOKIE_HTTPONLY does anybody know this?
I most android systems the SET-COOKIES shows up only on one of our 5.1 android systems its does not show the SET-COOKIES.
This might be some security setting, but we cant find out what and where, somebody knows this?
WE have this code now, in most android systems we see the Cookie_Httponly, but in one system it does not
URL url = new URL (urlAddress);
String COOKIES_HEADER = "Set-Cookie";
var connection = (HttpURLConnection)url.OpenConnection ();
try
{
var stream = connection.InputStream;
using (var reader = new StreamReader (stream))
{
var content = reader.ReadToEnd ();
Console.WriteLine(content);
}
var headerFields = connection.HeaderFields;
if( headerFields.ContainsKey(COOKIES_HEADER))
{
var cookiesHeader = headerFields [COOKIES_HEADER];
if (cookiesHeader != null)
{
foreach (String cookie in cookiesHeader)
{
var _c = HttpCookie.Parse (cookie) [0];
cookies[_c.Name] = _c.Value;
}
}
}
return true;
}

Unhandled exception: Input string was not in a correct format

I am getting this error though there are other posts as well but I am not getting a proper solution for my problem.
Debugger is pointing to this statement
id = Convert.ToInt32(s);
It works fine at beginning but now it is generating error. Following is the complete function. As a side note I am following N-tier architecture in Visual Studio 2013.
public List<ATMBO> GetDataFromFile() // get data from file and store it into object and pass to BLL !!!!
{
List<ATMBO> l = new List<ATMBO>();
// opening stream !!!
FileStream f = new FileStream("BankClient.txt", FileMode.Open);
StreamReader sr = new StreamReader(f);
if (!File.Exists("BankClient.txt"))
{
Console.WriteLine("{0} does not exist.", "BankClient.txt");
}
// Start reading from file
string record=sr.ReadLine();
//sr.ReadLine();
while((record = sr.ReadLine()) != null)
{
//record = sr.ReadLine();
// storing data from file to object!!!!
string [] data = record.Split(':');
//Console.WriteLine(data[0]);
ATMBO bo = new ATMBO();
string s = (data[0]);
int id = 0;
try
{
id = Convert.ToInt32(s);
}
catch (FormatException e)
{
Console.WriteLine("Input string is not a sequence of digits.");
}
catch (OverflowException e)
{
Console.WriteLine("The number cannot fit in an Int32.");
}
bo.ID1 = id;
bo.Login = data[1];
bo.Type = data[2];
string ss = (data[3]);
int blnc = Convert.ToInt32(ss);
bo.Balance = blnc;
bo.Status = data[4];
bo.Date = data[5];
bo.Pin = data[6];
l.Add(bo);
}
sr.Close();
f.Close();
return l;
}
Contents of my BankClient.txt file:
ID:Name:Type:Balance:Status:Date:Pin
00:Admin:Savings:500:Active:1/11/2014:111
01:Nabeel:Savings:0:Active:1/11/2014:222
02:Asad:Current:600:Active:2/11/2014:333
03:Aqsa:Current:-300:Active:3/11/2014:ABC
04:Umer:Savings:1000:Active:4/11/2014:444
05:Ali:Savings:1000:Active:4/11/2014:555

You need to add some error handling to your code to make sure there are actual values you can work with, such as
string [] data = record.Split(':');
if(data.length < 7)
Console.WriteLine("Data doesn't contain what was expected");
Better yet, instead of Convert.ToInt32 you can use TryParse
int id;
if(!int.TryParse(s, out id))
Console.WriteLine("Not a valid id");

Parsing performance of row data from files to SQL Server database

I have the PAF raw data in several files (list of all addresses in the UK).
My goal is to create a PostCode lookup in our software.
I have created a new database but there is no need to understand it for the moment.
Let's take a file, his extension is ".c01" and can be open with a text editor. The data in this file are in the following format :
0000000123A
With (according to the developer guide), 8 char for the KEY, 50 char for the NAME.
This file contains 2,449,652 rows (it's a small one !)
I create a Parsing class for this
private class SerializedBuilding
{
public int Key
{
get; set;
}
public string Name
{
get; set;
}
public bool isValid = false;
public Building ToBuilding()
{
Building b = new Building();
b.BuildingKey = Key;
b.BuildingName = Name;
return b;
}
private readonly int KEYLENGTH = 8;
private readonly int NAMELENGTH = 50;
public SerializedBuilding(String line)
{
string KeyStr = null;
string Name = null;
try
{
KeyStr = line.Substring(0, KEYLENGTH);
}
catch (Exception e)
{
Console.WriteLine("erreur parsing key line " + line);
return;
}
try
{
Name = line.Substring(KEYLENGTH - 1, NAMELENGTH);
}
catch (Exception e)
{
Console.WriteLine("erreur parsing name line " + line);
return;
}
int value;
if (!Int32.TryParse(KeyStr, out value))
return;
if (value == 0 || value == 99999999)
return;
this.Name = Name;
this.Key = value;
this.isValid = true;
}
}
I use this method to read the file
public void start()
{
AddressDataContext d = new AddressDataContext();
Count = 0;
string line;
// Read the file and display it line by line.
System.IO.StreamReader file =
new System.IO.StreamReader(filename);
SerializedBuilding sb = null;
Console.WriteLine("Number of line detected : " + File.ReadLines(filename).Count());
while ((line = file.ReadLine()) != null)
{
sb = new SerializedBuilding(line);
if (sb.isValid)
{
d.Buildings.InsertOnSubmit(sb.ToBuilding());
if (Count % 100 == 0)
d.SubmitChanges();
}
Count++;
}
d.SubmitChanges();
file.Close();
Console.WriteLine("building added");
}
I use Linq to SQL classes to insert data to my database. The connection string is the default one.
This seems to work, I have added 67200 lines. It just crashed but my questions are not about that.
My estimations :
33,647,015 rows to parse
Time needed for execution : 13 hours
It's a one-time job (just needs to be done on my sql and on the client server later) so I don't really care about performances but I think it can be interesting to know how it can be improved.
My questions are :
Is readline() and substring() the most powerful ways to read these huge files ?
Can the performance be improved by modifying the connection string ?

Encoder SDK 4 - Push to Publishing Point

I'm coding an application in c# using EC4 SP2 SDK.
I want to publish my file to a media server publishing point. I've searched and found 2 examples regarding seting up and auth on publishing points, but either are from older sdk's or do not work (and are for console). basicly my application doesn't encode nothing, as if it had nothing to encode.
When in degub mode checkpont i can see the correct properties for the source file and for the server.
The encoding process takes 0secs to process. I checked the logs on the server events and i get a warning "the security system has received and auth request that could not be decoded". I just havo no knowledge to break up further than this. Any help would be appreciated.
this is the piece of code:
private void broadcastSourceFileToMediaServer2()
{
using (LiveJob job = new LiveJob())
{
String filetoencode = #"c:\temp\niceday.wmv";
LiveFileSource filesource = job.AddFileSource(filetoencode);
filesource.PlaybackMode = FileSourcePlaybackMode.Loop;
job.ActivateSource(filesource);
job.ApplyPreset(LivePresets.VC1Broadband4x3);
//don't know which one is good to use
job.AcquireCredentials += new EventHandler<AcquireCredentialsEventArgs>(job_AcquireCredentials);
_myUserName = "indes";
_pw = PullPW("indes");
Uri url = new Uri("http://192.168.1.74:8080/live");
PushBroadcastPublishFormat pubpoint = new PushBroadcastPublishFormat();
pubpoint.PublishingPoint = url;
pubpoint.UserName = _myUserName;
pubpoint.Password = _pw;
job.PublishFormats.Add(pubpoint);
job.PreConnectPublishingPoint();
job.StartEncoding();
statusBox.Text = job.NumberOfEncodedSamples.ToString();
job.StopEncoding();
job.Dispose();
}
}
public static string _myUserName { get; set; }
public static SecureString _pw { get; set; }
//codificação de Password a enviar
private static SecureString PullPW(string pw)
{
SecureString s = new SecureString();
foreach (char c in pw) s.AppendChar(c);
return s;
}
static void job_AcquireCredentials(object sender, AcquireCredentialsEventArgs e)
{
e.UserName = _myUserName;
e.Password = _pw;
e.Modes = AcquireCredentialModes.None;
}

Progresses:
I managed to authenticate (at least get a positive audit event) on the server.
I changed from this:
//don't know which one is good to use
job.AcquireCredentials += new EventHandler<AcquireCredentialsEventArgs>(job_AcquireCredentials);
_myUserName = "indes";
_pw = PullPW("indes");
Uri url = new Uri("http://192.168.1.74:8080/live");
PushBroadcastPublishFormat pubpoint = new PushBroadcastPublishFormat();
pubpoint.PublishingPoint = url;
pubpoint.UserName = _myUserName;
pubpoint.Password = _pw;
To this:
job.AcquireCredentials += new EventHandler<AcquireCredentialsEventArgs>(job_AcquireCredentials);
_myUserName = #"mediaservername\user";
_pw = PullPW("user_password");
Uri url = new Uri("http://192.168.1.74:8080/live");
PushBroadcastPublishFormat pubpoint = new PushBroadcastPublishFormat();
pubpoint.PublishingPoint = url;
If you see on one side if had to include the domain (either domain or computername) before username. this changed the failed audit events on the server, so i could eliminate the manual credentials pubpoint.username and pubpoint.Password.
Now I'm just dealing with a lack of output format exception. On to it.

Sadly I dont have enough rep to comment, so I have to write it as an answer.
Due to you are starting a live job, in order to stream you should not call job.StopEncoding() right after StartEncoding. I think usually you would use an event to stop the encoding. If you start encoding and immediately stop it, it is only logical you have no, or only a very small output.

I changed your code to the following and it seems work well. I guess your problem is that you disposed the instance of LiveJob class. You have to keep the instance alive before it finished encoding the whole stream. So change the using part and remove the StopEncoding and Dispose will be OK.
private void broadcastSourceFileToMediaServer2()
{
LiveJob job = new LiveJob();
String filetoencode = #"c:\temp\niceday.wmv";
LiveFileSource filesource = job.AddFileSource(filetoencode);
filesource.PlaybackMode = FileSourcePlaybackMode.Loop;
job.ActivateSource(filesource);
job.ApplyPreset(LivePresets.VC1Broadband4x3);
//don't know which one is good to use
job.AcquireCredentials += new EventHandler<AcquireCredentialsEventArgs>(job_AcquireCredentials);
_myUserName = "indes";
_pw = PullPW("indes");
Uri url = new Uri("http://192.168.1.74:8080/live");
PushBroadcastPublishFormat pubpoint = new PushBroadcastPublishFormat();
pubpoint.PublishingPoint = url;
pubpoint.UserName = _myUserName;
pubpoint.Password = _pw;
job.PublishFormats.Add(pubpoint);
job.PreConnectPublishingPoint();
job.StartEncoding();
statusBox.Text = job.NumberOfEncodedSamples.ToString();
}
public static string _myUserName { get; set; }
public static SecureString _pw { get; set; }
//codificação de Password a enviar
private static SecureString PullPW(string pw)
{
SecureString s = new SecureString();
foreach (char c in pw) s.AppendChar(c);
return s;
}
static void job_AcquireCredentials(object sender, AcquireCredentialsEventArgs e)
{
e.UserName = _myUserName;
e.Password = _pw;
e.Modes = AcquireCredentialModes.None;
}
