Class HmacSecureHashAlgorithm1

Namespace
Cuemon.Security.Cryptography
Assembly
Cuemon.Security.Cryptography.dll

Provides a Hash-based Message Authentication Code (HMAC) by using the SHA1 hash function. This class cannot be inherited. Implements the KeyedCryptoHash<TAlgorithm>

Examples

The following example demonstrates how to compute an HMAC-SHA1 hash with .

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

namespace MyApp.Examples;

public static class HmacSecureHashAlgorithm1Example
{
    public static void Demonstrate()
    {
        var algorithm = new HmacSecureHashAlgorithm1(CreateSecret(), null);
        var result = algorithm.ComputeHash(Encoding.UTF8.GetBytes("Authenticate this message"));

        Console.WriteLine(result.GetBytes().Length);
        Console.WriteLine(result.ToBase64String());
    }

    private static byte[] CreateSecret() => Encoding.UTF8.GetBytes("docs-secret-sha1");
}

Constructors

HmacSecureHashAlgorithm1(byte[], Action<ConvertibleOptions>)

Initializes a new instance of the HmacSecureHashAlgorithm1 class.

public HmacSecureHashAlgorithm1(byte[] secret, Action<ConvertibleOptions> setup)

Parameters

secret byte[]

The secret key for HmacSecureHashAlgorithm1 encryption. The key can be any length, but if it is more than 64 bytes long it will be hashed (using SHA-1) to derive a 64-byte key. Therefore, the recommended size of the secret key is 64 bytes.

setup Action<ConvertibleOptions>

The ConvertibleOptions which need to be configured.
