Hello everyone,
I looked at the forum rules and I think it is not problem to ask my question. I just wonder that I can use specific algorithm with hashcat or not?

I write the dcryption c# code below. 'b5961257cyT5e3' salt string and I don't remember the secretPass and I gotta decrpyt some data.
I wrote a simple software for bruteforce but it is really very slow.

So, I want to ask that I am able to use hashcat for my problem or any idea about how I can solve my problem?

Thank you to all for your answer in advance.
 

Code:

public static string Dec(string CipheredText, string SecretPass)        {            RijndaelManaged managedRjdl = new RijndaelManaged();            try            {                Rfc2898DeriveBytes bytes = new Rfc2898DeriveBytes(SecretPass, Encoding.ASCII.GetBytes("b5961257cyT5e3"));                managedRjdl.Key = bytes.GetBytes(managedRjdl.KeySize / 8);                managedRjdl.IV = bytes.GetBytes(managedRjdl.BlockSize / 8);                ICryptoTransform transformCrypto = managedRjdl.CreateDecryptor(managedRjdl.Key, managedRjdl.IV);                using (MemoryStream streamM = new MemoryStream(Convert.FromBase64String(CipheredText)))                {                    using (CryptoStream streamC = new CryptoStream(streamM, transformCrypto, CryptoStreamMode.Read))                    {                        using (StreamReader reader = new StreamReader(streamC))                        {                            return reader.ReadToEnd();                        }                    }                }            }            finally            {                managedRjdl?.Clear();            }        }

There's no AES known plaintext attack module and unless the keyspace is largely decreased by some very good password "hint" it's not possible to crack the key based on it.
