php7.1 mcrypt_encrypt 用什么替代

[17771258]

现在程序中有这样一行代码

``` php

$encrypted = mcrypt_encrypt(
MCRYPT_RIJNDAEL_128,
"1234567890123456",
"123456",
MCRYPT_MODE_CBC,
"1234567890123456"
);

echo base64_encode($encrypted);

// 得到的结果为 QEwd/DWmy/4yGncCqBofQQ==

```
但是在 `php7.1.*` 中 `mcrypt_encrypt` 函数已经不允许使用，所以想请问各位我应该用什么方法得到同样的结果，在网上搜索有人说用 `openssl_encrypt` 函数替代，但是我测试了一圈还是不能得到正确的结果；

``` php

echo openssl_encrypt(
"123456",
"AES-128-CBC",
"1234567890123456",
null,
"1234567890123456"
);

// 得到的结果为 1jdzWuniG6UMtoa3T6uNLA==

```
各位有遇到过这样的问题吗，最后是怎么解决的。

hash('sha512','xxx')不好吗

null 改成 OPENSSL_ZERO_PADDING 试试

http://php.net/manual/en/migration71.deprecated.php

The mcrypt extension has been abandonware for nearly a decade now, and was also fairly complex to use. It has therefore been deprecated in favour of OpenSSL, where it will be removed from the core and into PECL in PHP 7.2.

但貌似有个问题 openssl_decrypt 不支持 PKCS5
