이 온라인 도구에서 사용하는 AES 암호화를 복제하는 방법

http://aes.online-domain-tools.com/

CBC를 사용하여 C #으로이 암호화를 복제하려고하지만 시도해도 동일한 결과를 얻지 못합니다.

지금까지 내 코드 :

    private byte[] hex2bytes(string s)
    {
        return Enumerable.Range(0, s.Length)
                         .Where(x => x % 2 == 0)
                         .Select(x => Convert.ToByte(s.Substring(x, 2), 16))
                         .ToArray();        
    }

private AesCryptoServiceProvider GetProvider(byte[] key)
{
    AesCryptoServiceProvider result = new AesCryptoServiceProvider();
    result.BlockSize = 128;
    result.KeySize = 128;
    result.Mode = CipherMode.CBC;
    result.Padding = PaddingMode.PKCS7;

    result.GenerateIV();
    //result.IV = new byte[] { 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0};
    result.IV = hex2bytes("ad77d666311839f5665aeb2e42f64542");

    byte[] RealKey = GetKey(key, result);
    _key = Encoding.ASCII.GetString(RealKey);
    result.Key = RealKey;
    // result.IV = RealKey;
    return result;
}

private byte[] GetKey(byte[] suggestedKey, SymmetricAlgorithm p)
{
    byte[] kRaw = suggestedKey;
    List<byte> kList = new List<byte>();

    for (int i = 0; i < p.LegalKeySizes[0].MinSize; i += 8)
    {
        kList.Add(kRaw[(i / 8) % kRaw.Length]);
    }
    byte[] k = kList.ToArray();
    return k;
}
