How to generate Hash in asp.net C#

You can generate the hash without initializing the variables first.see the code: 

using System.Security.Cryptography;
using System.Text;

// Set the values directly
string requestId = "123456789";
string status = "success";
string responseCode = "200";
string aadhaarId = "123456789012";
string availableBalance = "1000";
string salt = "mysalt123";

// Concatenate values into a string
string message = requestId + "#" + status + "#" + responseCode + "#" + aadhaarId + "#" + availableBalance + "#" + salt;

// Convert message string to byte array
byte[] messageBytes = Encoding.UTF8.GetBytes(message);

// Create SHA-512 hash object
SHA512 sha512 = SHA512.Create();

// Compute hash value
byte[] hashBytes = sha512.ComputeHash(messageBytes);

// Convert hash to string
string hashString = BitConverter.ToString(hashBytes).Replace("-", "");

The values for `requestId`, `status`, `responseCode`, `aadhaarId`, `availableBalance`, and `salt` are set directly in the code. You can replace these values with the appropriate variables or values from your own code.

Hi Jagapathibabu,

check this. 

using System;
using System.Text;
using System.Security.Cryptography;
 
public class Example
{
    static string ComputeSHA512(string s)
    {
        StringBuilder sb = new StringBuilder();
        using (SHA512 sha512 = SHA512.Create())
        {
            byte[] hashValue = sha512.ComputeHash(Encoding.UTF8.GetBytes(s));
            foreach (byte b in hashValue) {
                sb.Append($"{b:X2}");
            }
        }
 
        return sb.ToString();
    }
 
    public static void Main()
    {
        string hashValue = ComputeSHA512("Some string");
        Console.WriteLine(hashValue);
    }
}

Without Initialize variables How can I generate The Hash Sir....

Hi Jagapathibabu,

Do refer below links

using System.Security.Cryptography;
using System.Text;

// Initialize variables
string requestId = "123456789";
string status = "success";
string responseCode = "200";
string aadhaarId = "123456789012";
string availableBalance = "1000";
string salt = "mysalt123";

// Concatenate values into a string
string message = requestId + "#" + status + "#" + responseCode + "#" + aadhaarId + "#" + availableBalance + "#" + salt;

// Convert message string to byte array
byte[] messageBytes = Encoding.UTF8.GetBytes(message);

// Create SHA-512 hash object
SHA512 sha512 = SHA512.Create();

// Compute hash value
byte[] hashBytes = sha512.ComputeHash(messageBytes);

// Convert hash to string
string hashString = BitConverter.ToString(hashBytes).Replace("-", "");
