Need equivalent c# code for implementation

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;
}
