无法使用AES / ECB / PKCS5Padding将加密方法从Java复制到PHP

        System.out.println("asp secret encrypted:");
        System.out.println(enc_asp_secret);     
    }
}

我碰巧在StackOverflow中看到了一个非常相似的帖子而没有答案

Cannot replicate an AES 256 encryption code from Java to PHP [duplicate]

与另一个不同的问题标记为重复。

我已经尝试了几个php代码，但它没有成功。

我会为此加起来，因为我多年来一直试着这个。

免责声明：使用上述问题中的相同代码片段，因为这个代码片段更清晰。

添加我试过的PHP代码

class AtomAES {

public function encrypt($data = '', $key = NULL, $salt = "") {
    if($key != NULL && $data != "" && $salt != ""){

        $method = "AES-256-CBC";

        //Converting Array to bytes
        $iv = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15];
        $chars = array_map("chr", $iv);
        $IVbytes = join($chars);


        $salt1 = mb_convert_encoding($salt, "UTF-8"); //Encoding to UTF-8
        $key1 = mb_convert_encoding($key, "UTF-8"); //Encoding to UTF-8

        //SecretKeyFactory Instance of PBKDF2WithHmacSHA1 Java Equivalent
        $hash = openssl_pbkdf2($key1,$salt1,'256','65536', 'sha1'); 

        $encrypted = openssl_encrypt($data, $method, $hash, OPENSSL_RAW_DATA, $IVbytes);

        return bin2hex($encrypted);
    }else{
        return "String to encrypt, Salt and Key is required.";
    }
}

public function decrypt($data="", $key = NULL, $salt = "") {
    if($key != NULL && $data != "" && $salt != ""){
        $dataEncypted = hex2bin($data);
        $method = "AES-256-CBC";

        //Converting Array to bytes
        $iv = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15];
        $chars = array_map("chr", $iv);
        $IVbytes = join($chars);

        $salt1 = mb_convert_encoding($salt, "UTF-8");//Encoding to UTF-8
        $key1 = mb_convert_encoding($key, "UTF-8");//Encoding to UTF-8

        //SecretKeyFactory Instance of PBKDF2WithHmacSHA1 Java Equivalent
        $hash = openssl_pbkdf2($key1,$salt1,'256','65536', 'sha1'); 

        $decrypted = openssl_decrypt($dataEncypted, $method, $hash, OPENSSL_RAW_DATA, $IVbytes);
        return $decrypted;
    }else{

        return "Encrypted String to decrypt, Salt and Key is required.";

    }
}

}

我无法使用此PHP解密使用java生成的字符串

更新

这是我尝试使用上面的java代码进行加密的文本和密钥
