Need equivalent c# code for implementation

Question

I have one .net application where I need to call an API. That API needs value to be encrypted with AES algorithm with Hashing. That API is developed in Java. I am not able to find equivalent .net code to encrypt and decrypt as done in Java..

 

Attached Java code here.

 

Need equivalent c# code.

 

I was trying below code but it didnt work

public byte[] AES_Encrypt(byte[] bytesToBeEncrypted, byte[] passwordBytes) {
 byte[] encryptedBytes = null;
 // Set your salt here, change it to meet your flavor:
 // The salt bytes must be at least 8 bytes.
 byte[] saltBytes = new byte[] {
  1,
  2,
  3,
  4,
  5,
  6,
  7,
  8
 };
 using(MemoryStream ms = new MemoryStream()) {
  using(RijndaelManaged AES = new RijndaelManaged()) {
   AES.KeySize = 256;
   AES.BlockSize = 128;
   var key = new Rfc2898DeriveBytes(passwordBytes, saltBytes, 1000);
   AES.Key = key.GetBytes(AES.KeySize / 8);
   AES.IV = key.GetBytes(AES.BlockSize / 8);
   AES.Mode = CipherMode.CBC;
   using(var cs = new CryptoStream(ms, AES.CreateEncryptor(), CryptoStreamMode.Write)) {
    cs.Write(bytesToBeEncrypted, 0, bytesToBeEncrypted.Length);
    cs.Close();
   }
   encryptedBytes = ms.ToArray();
  }
 }
 return encryptedBytes;
}
public byte[] AES_Decrypt(byte[] bytesToBeDecrypted, byte[] passwordBytes) {
 byte[] decryptedBytes = null;
 // Set your salt here, change it to meet your flavor:
 // The salt bytes must be at least 8 bytes.
 byte[] saltBytes = new byte[] {
  1,
  2,
  3,
  4,
  5,
  6,
  7,
  8
 };
 using(MemoryStream ms = new MemoryStream()) {
  using(RijndaelManaged AES = new RijndaelManaged()) {
   AES.KeySize = 256;
   AES.BlockSize = 128;
   var key = new Rfc2898DeriveBytes(passwordBytes, saltBytes, 1000);
   AES.Key = key.GetBytes(AES.KeySize / 8);
   AES.IV = key.GetBytes(AES.BlockSize / 8);
   AES.Mode = CipherMode.CBC;
   using(var cs = new CryptoStream(ms, AES.CreateDecryptor(), CryptoStreamMode.Write)) {
    cs.Write(bytesToBeDecrypted, 0, bytesToBeDecrypted.Length);
    cs.Close();
   }
   decryptedBytes = ms.ToArray();
  }
 }
 return decryptedBytes;
}
