尝试在java中使用AES加密时出错

Question

我正在尝试构建一个Java程序，该程序先压缩文件，然后使用AES加密对文件进行加密。但是，我在加密过程中遇到以下错误：

Exception in thread "main" java.security.NoSuchAlgorithmException: Cannot find any provider supporting PBKDF2WithHmacSHA256
at java.base/javax.crypto.Cipher.getInstance(Cipher.java:574)
at MyJavaProject.zip.encryptFile(zip.java:75)
at MyJavaProject.zip.main(zip.java:58)

我在下面包含了我的代码。它应该压缩我指向它的文件，然后对它进行加密，并保存用于salt和IV的字节，以便我以后可以解密。我使用的是Java16，我的JRE是JavaSE-12

class zip {
    public static void main(String[] args) throws IOException, InvalidKeyException, NoSuchPaddingException,
            NoSuchAlgorithmException, InvalidAlgorithmParameterException, BadPaddingException,
            IllegalBlockSizeException, InvalidKeySpecException {
        FileInputStream fis = new FileInputStream("texty.txt");
        FileOutputStream fos = new FileOutputStream("texty(comp)");
        DeflaterOutputStream dos = new DeflaterOutputStream(fos);

        int data;
        while ((data = fis.read()) != -1) {
            dos.write(data);
        }

        fis.close();
        dos.close();

        SecureRandom random = new SecureRandom();
        byte[] salt = new byte[16];
        random.nextBytes(salt);
        SecretKey key = getKeyFromPassword("Password", salt.toString());
        String algorithm = "AES/CBC/PKCS5Padding";
        byte[] iv = new byte[16];
        new SecureRandom().nextBytes(iv);
        IvParameterSpec Iv = new IvParameterSpec(iv);
        encryptFile(algorithm, key, Iv, new File("texty(comp)"), new File("texty(compNenc)"));
        FileOutputStream fs = new FileOutputStream(new File("intravenus"));
        BufferedOutputStream bos = new BufferedOutputStream(fs);
        bos.write(iv);
        bos.close();
        FileOutputStream fs2 = new FileOutputStream(new File("pepper"));
        BufferedOutputStream bos2 = new BufferedOutputStream(fs2);
        bos2.write(salt);
        bos2.close();
    }

    public static void encryptFile(String algorithm, SecretKey key, IvParameterSpec iv, File inputFile, File outputFile)
            throws IOException, NoSuchPaddingException, NoSuchAlgorithmException, InvalidAlgorithmParameterException,
            InvalidKeyException, BadPaddingException, IllegalBlockSizeException {

        Cipher cipher = Cipher.getInstance(algorithm);
        cipher.init(Cipher.ENCRYPT_MODE, key, iv);
        FileInputStream inputStream = new FileInputStream(inputFile);
        FileOutputStream outputStream = new FileOutputStream(outputFile);
        byte[] buffer = new byte[64];
        int bytesRead;
        while ((bytesRead = inputStream.read(buffer)) != -1) {
            byte[] output = cipher.update(buffer, 0, bytesRead);
            if (output != null) {
                outputStream.write(output);
            }
        }
        byte[] outputBytes = cipher.doFinal();
        if (outputBytes != null) {
            outputStream.write(outputBytes);
        }
        inputStream.close();
        outputStream.close();
    }

    public static SecretKey getKeyFromPassword(String password, String salt)
            throws NoSuchAlgorithmException, InvalidKeySpecException {

        SecretKeyFactory factory = SecretKeyFactory.getInstance("PBKDF2WithHmacSHA256");
        KeySpec spec = new PBEKeySpec(password.toCharArray(), salt.getBytes(), 65536, 256);
        SecretKey secret = new SecretKeySpec(factory.generateSecret(spec).getEncoded(), "AES");
        return secret;
    }

}

更新： 谢谢你帮助我解决了最初的错误，但是现在我有了一个新的错误，我还不太了解。当我尝试下载为salt和IV存储的字节，并尝试解密文件时，我收到以下错误消息：

Exception in thread "main" javax.crypto.BadPaddingException: Given final block not properly padded. Such issues can arise if a bad key is used during decryption.

下面列出了我的解密文件代码。如果有人能帮忙，我将不胜感激
