Enum AesSize

Namespace

Cuemon.Security.Cryptography

Assembly

Cuemon.Security.Cryptography.dll

Specifies the size of the Advanced Encryption Standard (AES) symmetric algorithm.

public enum AesSize

Fields

Aes128 = 0

The Advanced Encryption Standard (AES) symmetric algorithm with a 128 bit key.

Aes192 = 1

The Advanced Encryption Standard (AES) symmetric algorithm with a 192 bit key.

Aes256 = 2

The Advanced Encryption Standard (AES) symmetric algorithm with a 256 bit key.

Examples

The following example demonstrates how to select AES key sizes using the AesSize enumeration when generating cryptographic keys.

using System;
using Cuemon.Security.Cryptography;

namespace MyApp.Security;

public class AesSizeExample
{
    public void Demonstrate()
    {
        // AesSize specifies the key size for the AES symmetric algorithm:
        //   Aes128 = 128-bit key (16 bytes)
        //   Aes192 = 192-bit key (24 bytes)
        //   Aes256 = 256-bit key (32 bytes, default)

        // Generate a 256-bit key (default when no options are specified)
        byte[] defaultKey = AesCryptor.GenerateKey();
        Console.WriteLine($"Default key length: {defaultKey.Length} bytes"); // 32

        // Generate a 128-bit key using AesSize.Aes128
        byte[] key128 = AesCryptor.GenerateKey(o => o.Size = AesSize.Aes128);
        Console.WriteLine($"128-bit key length: {key128.Length} bytes"); // 16

        // Generate a 192-bit key using AesSize.Aes192
        byte[] key192 = AesCryptor.GenerateKey(o => o.Size = AesSize.Aes192);
        Console.WriteLine($"192-bit key length: {key192.Length} bytes"); // 24

        // Generate a 256-bit key explicitly using AesSize.Aes256
        byte[] key256 = AesCryptor.GenerateKey(o => o.Size = AesSize.Aes256);
        Console.WriteLine($"256-bit key length: {key256.Length} bytes"); // 32

        // Compare enum values directly
        AesSize size = AesSize.Aes256;
        Console.WriteLine($"Selected size: {size}"); // Aes256
        Console.WriteLine($"Is Aes256 selected: {size == AesSize.Aes256}"); // True
