I am experimenting with cryptography and I was wondering if somebody has some suggestion how I could improve my code and methodology.

I want my process to generate more securely the cryptography process if that is possible.

import java.security.GeneralSecurityException;
import java.security.Key;
import java.util.Base64;
import javax.crypto.Cipher;
import javax.crypto.spec.SecretKeySpec;
public class Crypto_Security {
  static public final String CRY_ALGO = "AES";
  static public String encrypt(byte[] pSecret, String pValue) throws GeneralSecurityException {
    Key aesKey = new SecretKeySpec(pSecret, CRY_ALGO);
    Cipher cipher = Cipher.getInstance(CRY_ALGO);
    cipher.init(Cipher.ENCRYPT_MODE, aesKey);
    byte[] encrypted = cipher.doFinal(pValue.getBytes());
    Base64.Encoder encoder = Base64.getEncoder();
    return encoder.encodeToString(encrypted);
  static public String decrypt(byte[] pSecret, String pEncrypted) throws GeneralSecurityException {
    SecretKeySpec skeySpec = new SecretKeySpec(pSecret, CRY_ALGO);
    Cipher cipher = Cipher.getInstance(CRY_ALGO);
    cipher.init(Cipher.DECRYPT_MODE, skeySpec);
    byte[] original = cipher.doFinal(Base64.getDecoder().decode(pEncrypted));
    return new String(original);
  static public void main( String[] args ) {
    try {
      System.out.println("enc " + encrypt( "2144226321110063".getBytes() , "serial.txt" ));
      System.out.println("dcr " + decrypt( "2144226321110063".getBytes() , "oLQgEUxg3Z3zMSsSkiKpBg==" ));
    } catch( GeneralSecurityException e ) {
  private Crypto_Security() {
