mcrypt_module_open（） 有替代方案可用吗？

要用openssl代替mcrypt
$encrypted = openssl_encrypt($text, 'AES-256-CBC', $this->key, OPENSSL_RAW_DATA | OPENSSL_ZERO_PADDING, $iv);

非常感谢了

php7.2.1-nts（windows) Prpcrypt类中的构造函数写法是一个坑，难道就我发现吗，改成__construct就行了，也不用替换任何函数

是因为这个sdk太老了

pkcs7Encoder.php 文件，解密解密两个函数替换为：

public function encrypt($text, $corpid)
{
	try {
		$random = $this->getRandomStr();
		$text = $random . pack("N", strlen($text)) . $text . $corpid;
		$iv = substr($this->key, 0, 16);
		$pkc_encoder = new PKCS7Encoder;
		$text = $pkc_encoder->encode($text);
		$encrypted = openssl_encrypt($text, 'AES-256-CBC', $this->key, OPENSSL_RAW_DATA | OPENSSL_ZERO_PADDING, $iv);

		//print(base64_encode($encrypted));
		//使用BASE64对加密后的字符串进行编码
		return array(ErrorCode::$OK, base64_encode($encrypted));
	} catch (Exception $e) {
		print $e;
		return array(ErrorCode::$EncryptAESError, null);
	}
}


public function decrypt($encrypted, $corpid)
{
	try {
		$ciphertext_dec = base64_decode($encrypted);
		$iv = substr($this->key, 0, 16);
		$decrypted = openssl_decrypt($ciphertext_dec, 'AES-256-CBC', $this->key, OPENSSL_RAW_DATA | OPENSSL_ZERO_PADDING, $iv);
	} catch (Exception $e) {
		return array(ErrorCode::$DecryptAESError, null);
	}
	try {
		//去除补位字符
		$pkc_encoder = new PKCS7Encoder;
		$result = $pkc_encoder->decode($decrypted);
		//去除16位随机字符串,网络字节序和AppId
		if (strlen($result) < 16)
			return "";
		$content = substr($result, 16, strlen($result));
		$len_list = unpack("N", substr($content, 0, 4));
		$xml_len = $len_list[1];
		$xml_content = substr($content, 4, $xml_len);
		$from_corpid = substr($content, $xml_len + 4);
	} catch (Exception $e) {
		print $e;
		return array(ErrorCode::$IllegalBuffer, null);
	}
	if ($from_corpid != $corpid)
		return array(ErrorCode::$ValidateCorpidError, null);
	return array(0, $xml_content);
}
