KeyedHashFactory

Examples

The following example shows how to compute an HMAC-SHA256 hash for message authentication using KeyedHashFactory. It creates a keyed hash algorithm with a secret key, hashes an input string, and prints the hexadecimal digest.

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

namespace Cuemon.Security.Cryptography;

public class KeyedHashFactoryExample
{
    public void Demonstrate()
    {
        var secret = Encoding.UTF8.GetBytes("my-secret-key");
        var hmac = KeyedHashFactory.CreateHmacCryptoSha256(secret);
        var input = "Message to authenticate";
        var hash = hmac.ComputeHash(Encoding.UTF8.GetBytes(input));
        Console.WriteLine($"HMAC-SHA256: {BitConverter.ToString(hash.To<byte[]>(bytes => bytes)).Replace("-", "")}");
    }
}

Methods

Name	Description
CreateHmacCrypto(byte[], KeyedCryptoAlgorithm, Action<ConvertibleOptions>)	Creates an instance of a HMAC cryptographic implementation that derives from KeyedCryptoHash<TAlgorithm> with the specified algorithm. Default is HmacSecureHashAlgorithm256.
CreateHmacCryptoMd5(byte[], Action<ConvertibleOptions>)	Creates an instance of HmacMessageDigest5.
CreateHmacCryptoSha1(byte[], Action<ConvertibleOptions>)	Creates an instance of HmacSecureHashAlgorithm1.
CreateHmacCryptoSha256(byte[], Action<ConvertibleOptions>)	Creates an instance of HmacSecureHashAlgorithm256.
CreateHmacCryptoSha384(byte[], Action<ConvertibleOptions>)	Creates an instance of HmacSecureHashAlgorithm384.
CreateHmacCryptoSha512(byte[], Action<ConvertibleOptions>)	Creates an instance of HmacSecureHashAlgorithm512.
