Read text from MS Word and Save/Retrive in Encrypt Decrypt format using C# in ASp.Net

Hi! I used Read content (text) from Word document and insert into Database in ASP.Net it’s worked without problem. But I want use Encrypt method for this.

private string Encrypt(string clearText)
        {
            string EncryptionKey = "MAKV2SPBNI99212";
            byte[] clearBytes = Encoding.Unicode.GetBytes(clearText);
            using (Aes encryptor = Aes.Create())
            {
                Rfc2898DeriveBytes pdb = new Rfc2898DeriveBytes(EncryptionKey, new byte[]
                 {
                  0x49,0x76,0x61,0x6e,0x20,0x4d,0x65,0x64,0x76,0x65,0x64,0x65,0x76});
                encryptor.Key = pdb.GetBytes(32);
                encryptor.IV = pdb.GetBytes(16);
                using (MemoryStream ms = new MemoryStream())
                {
                    using (CryptoStream cs = new CryptoStream(ms, encryptor.CreateEncryptor(), CryptoStreamMode.Write))
                    {
                        cs.Write(clearBytes, 0, clearBytes.Length);
                        cs.Close();
                    }
                    clearText = Convert.ToBase64String(ms.ToArray());
                }
            }
            return clearText;
        }

In Grid View  show below result.  For example:

Input text from MS Word:

@1.The capital of India.

$A) Dushanbe; $B) Moscow;  ©C) Delhi; $D) Kabul;

Output result:

1. J9diXJiVz+V3oqfcvqy2597Z/fbt9cLmFRh7Vyl3rNdjwatgJLSbHxuf0hcE4S/K

A) 4rSbWUeVqKg/C4YOcp4fh+0EZM4aTH9epTXpSpu586Y=

B) cLJciGSuTwferfP2s1r60g==
