SHA-256(Source Code in C# using .Net in-built Cryptography library) - Part II

.Net Framework provides in built support for various hash functions like MD-5, SHA-1, SHA-256 etc...

ComputeHash method Computes the hash value to the specified byte array.

Below are the overloaded methods to Compute Hash using SHA-256 class in System.Security.Cryptography  library

public byte[] ComputeHash(byte[] buffer)

public byte[] ComputeHash(Stream inputStream)

public byte[] ComputeHash(byte[] buffer, int offset, int count)

	using System;
	using System.Security.Cryptography;
	using System.Text;
	namespace SecureHashingProject
	{
	public class SecureHashingAlgorithm256
	{
	static void Main()
	{
	var data = Console.ReadLine();
	if (string.IsNullOrEmpty(data))
	{
	Console.WriteLine("No data to generate hash");
	return;
	}
	var sha256 = SHA256.Create();
	var bytes = sha256.ComputeHash(Encoding.UTF8.GetBytes(data));
	var builder = new StringBuilder();
	foreach (var b in bytes)
	{
	builder.Append(b.ToString("x2"));
	}
	Console.WriteLine($"Hash: {builder}");
	Console.ReadLine();
	}
	}
	}
