Sample

simple encrypt and decrypt code.

String plainText = "test text abcdefg.";
byte[] plainByte = System.Text.Encoding.ASCII.GetBytes(plainText);

// Speck ECB mode
using (SymmetricAlgorithm algo = new Speck())
{
    algo.BlockSize = 128;
    algo.KeySize = 128;
    
    algo.GenerateKey();
    using (ICryptoTransform encryptor = algo.CreateEncryptor() , decryptor = algo.CreateDecryptor())
    {
        byte[] plainEnc = encryptor.TransformFinalBlock(plainByte, 0, plainByte.Length);
        byte[] plainDec = decryptor.TransformFinalBlock(plainEnc, 0, plainEnc.Length);
        Console.WriteLine(System.Text.Encoding.ASCII.GetString(plainDec));
        Console.WriteLine();
    }
}

// Speck CTR mode
using (SymmetricAlgorithm algo = new SpeckCTR())
{
    algo.BlockSize = 128;
    algo.KeySize = 128;
    
    algo.GenerateIV();
    algo.GenerateKey();
    using (ICryptoTransform encryptor = algo.CreateEncryptor() , decryptor = algo.CreateDecryptor())
    {
        byte[] plainEnc = encryptor.TransformFinalBlock(plainByte, 0, plainByte.Length);
        byte[] plainDec = decryptor.TransformFinalBlock(plainEnc, 0, plainEnc.Length);
        Console.WriteLine(System.Text.Encoding.ASCII.GetString(plainDec));
        Console.WriteLine();
    }
}
