What is pin block in c#
I this article you will learn, how to create pin block in c#. A block of data used to encapsulate a PIN during processing. The PIN block format defines the content of the PIN block and how it is processed to retrieve the PIN. The PIN block is composed of the PIN, the PIN length, and may contain subset of the PAN.
What is pin block in HSM?
Personal identification number (PIN) blocks are 64-bit strings that encode a PIN ready for encryption and secure transmission. in banking networks. These networks employ tamper-proof hardware security modules (HSMs) to perform sensitive cryptographic.
How API on POS creating pin block?
public static byte[] GetPinBlock(string CardNumber, string PIN)
{
CardNumber = "2222222222222222";
PIN = "1234";
string hexPINBlock = ( ("0" + PIN.Length + PIN).PadRight(16, 'F'));
string CNumber = CardNumber.Substring(0, CardNumber.Length - 1); // to skip right most check digit
string hexCardlock = ("0000" + CNumber.Substring(CNumber.Length - 12));
long dec1 = Convert.ToInt64(hexPINBlock, 16);
long dec2 = Convert.ToInt64(hexCardlock, 16);
long result = dec1 ^ dec2;
string hexResult = result.ToString("X");//PinBlock=041216DDDDDDDDDD
if (hexResult.Length < 16)
{
hexResult = "0" + hexResult;
}
int NumberChars = hexResult.Length;
byte[] bytes = new byte[NumberChars / 2];
for (int i = 0; i < NumberChars; i += 2)
bytes[i / 2] = Convert.ToByte(hexResult.Substring(i, 2), 16);
return bytes;
}
What is pin block in c#
C# is a programming language developed by Microsoft that runs on the .NET Framework. C# is used to develop web, desktop, mobile, games and much more application.
C# is a object-oriented programming language developed by Microsoft within its .NET Framework. Led by Anders Hejlsberg, your basic C# programming
and will also take you through various advanced concepts related to C# programming language.
C# such as control statements, objects and classes, inheritance, constructor, destructor, this, static, sealed, polymorphism, abstraction, abstract class, interface, File IO, Collections, namespace, encapsulation, properties, indexer, arrays, strings, regex, exception handling, multithreading etc.
For example...
using System;
namespace MinifyCode
{
class Program
{
static void Main(string[] args)
{
Console.WriteLine("Hello Minify Code");
}
}
}
Output: Hello Minify Code
In this article you will learn, what is server side controls. We will discuss each of these objects in due time. In this tutorial we will explore the Server object, the Request object, and the Response object.

Server Object
The Server object in Asp.NET is an instance of the System.Web.HttpServerUtility class. The HttpServerUtility class provides numerous properties and methods to perform many type of jobs.
Methods and Properties of the Server object
The methods and properties of the HttpServerUtility class are exposed through the intrinsic Server object provided by ASP.NET.
