Crypto Node.js : PBEWithHmacSHA512AndAES_128 - node.js

Question

I am trying to implement an equivalent of PBEWithHmacSHA512AndAES_128 crypt algorithm from Java for a node.js project.
I basically need to encrypt a string using a cipher made by that algorithm.
Any help is appreciated. Thanks in advance.
This is the snippet of code I have written in Java
public final static String ALGO_VIDEO_ENCRYPTOR = "PBEWithHmacSHA512AndAES_128";
static String password = "EncryptionSecretKey" ;
static byte[] salt = "NewSaltTest".getBytes() ;
static int iterCount = 12288 ;
static int derivedKeyLength = 256 ;
public static SecretKey encryptionKey;
public static SecretKey generateSecretKey(){
SecretKey key=null;
try {
salt=Arrays.copyOf(salt,128);
KeySpec spec = new PBEKeySpec(password.toCharArray(), salt, iterCount, derivedKeyLength * 8);
SecretKeyFactory skf = SecretKeyFactory.getInstance(ALGO_VIDEO_ENCRYPTOR);
key = skf.generateSecret(spec);
}catch (Exception e){
System.out.println(e);
}
return key;
}
public static String encryptString(SecretKey key, String input)
{
byte[] encrypted=null;
try {
byte[] iv = new byte[] { (byte) 0x8E, 0x12, 0x39, (byte) 0x9C,
0x07, 0x72, 0x6F, 0x5A, (byte) 0x8E, 0x12, 0x39, (byte) 0x9C,
0x07, 0x72, 0x6F, 0x5A };
IvParameterSpec ivSpec = new IvParameterSpec(iv);
PBEParameterSpec parameterSpec = new PBEParameterSpec(salt, iterCount, ivSpec);
Cipher cipher = Cipher.getInstance(ALGO_VIDEO_ENCRYPTOR);
cipher.init(Cipher.ENCRYPT_MODE, key,parameterSpec);
String charSet = "UTF-8";
byte[] in = input.getBytes(charSet);
encrypted = cipher.doFinal(in);
} finally {
String encStr = new String(Base64.getEncoder().encode(encrypted));
return encStr;
}
}
public static String decryptString(SecretKey key, String input) throws UnsupportedEncodingException {
byte[] decrypted=null;
try {
byte[] iv = new byte[] { (byte) 0x8E, 0x12, 0x39, (byte) 0x9C,
0x07, 0x72, 0x6F, 0x5A, (byte) 0x8E, 0x12, 0x39, (byte) 0x9C,
0x07, 0x72, 0x6F, 0x5A };
IvParameterSpec ivSpec = new IvParameterSpec(iv);
PBEParameterSpec parameterSpec = new PBEParameterSpec(salt, iterCount, ivSpec);
Cipher cipher = Cipher.getInstance(ALGO_VIDEO_ENCRYPTOR);
cipher.init(Cipher.DECRYPT_MODE, key, parameterSpec);
byte[] enc = Base64.getDecoder().decode(input);
decrypted = cipher.doFinal(enc);
} catch (Exception e){
System.out.println("Decrypt error"+e);
}finally {
String charSet = "UTF-8";
String plainStr = new String(decrypted, charSet);
return plainStr;
}
}
I am aware that the equivalence of this algorithm will basically derive a 256-bit AES key using salted PBKDF2 and then encrypt the stored key using AES/CBC/PKCS5Padding with that key. (ref - https://neilmadden.blog/2017/11/17/java-keystores-the-gory-details/)
