SHA256 C# with Example

using System; 
using System.Security.Cryptography; 
using System.Text; 
namespace ConsoleApplication1 
{ 
class Program 
{ 
static void Main(string[] args) 
{ 
string source = "Hello World!"; 
using (SHA256 sha256Hash = SHA256.Create()) 
{ 
//From String to byte array 
byte[] sourceBytes = Encoding.UTF8.GetBytes(source); 
byte[] hashBytes = sha256Hash.ComputeHash(sourceBytes); 
string hash = BitConverter.ToString(hashBytes).Replace("-", String.Empty); 
Console.WriteLine("The SHA256 hash of " + source + " is: " + hash); 
} 
} 
} 
} 
Output: 
The SHA256 hash of Hello World! is:
