Question

How to generate Hash in asp.net C#? Example: SHA512(requestId + "#" + status + "#"+ responseCode + "#" + aadhaarId + "#" + availableBalance + "#" salt)

Rajkiran Swain · Answer

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("-", "");

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); } }
