PHP encrypt and JAVA decrypt with openssl and AES-128-CBC

decrypt.java

    public static String decrypt(@NotNull String input, @NotNull String key){
        byte[] bytes = Base64.decodeBase64(input);
        if(bytes.length < 17) {
            return null;
        }

        byte[] ivBytes = Arrays.copyOfRange(bytes, 0, 16);
        byte[] contentBytes = Arrays.copyOfRange(bytes, 16, bytes.length);


        try {
            Cipher ciper = Cipher.getInstance("AES/CBC/PKCS5Padding");

            SecretKeySpec keySpec = new SecretKeySpec(key.getBytes("UTF-8"),"AES");
            IvParameterSpec iv = new IvParameterSpec(ivBytes,0, ciper.getBlockSize());

            ciper.init(Cipher.DECRYPT_MODE, keySpec, iv);
            return new String(ciper.doFinal(contentBytes));
        } catch (
            NoSuchAlgorithmException |
            NoSuchPaddingException |
            UnsupportedEncodingException |
            InvalidAlgorithmParameterException |
            InvalidKeyException |
            IllegalBlockSizeException |
            BadPaddingException ignored
            ) {
        }

        return null;
    }

encrypt.php

        $iv = openssl_random_pseudo_bytes(16, $secure);
        if (false === $secure || false === $iv) {
            throw new \RuntimeException('iv generation failed');
        }

        $data = $iv . openssl_encrypt($data, 'AES-128-CBC', $this->key, OPENSSL_RAW_DATA, $iv);

sorry my fault, everything is working fine, had an issue with file permissions.
