Php 如何发布sha512加密数据

我需要帮助我的PHP脚本。我需要以加密方式发布某些字段，如invoiceid、firstname、email等。校验和的公式是

sha512 (key|txnid|amount|productinfo|firstname|email|udf1|udf2|udf3|udf4|udf5||||||<SALT>)

sha512（关键字| txnid |金额|产品信息|名字|电子邮件| udf1 | udf2 | udf3 | udf4 | udf5 | | | | | |

我需要通过sha512发布上述变量。我不能这样做。请帮忙。我是一个学习者，我不擅长PHP

这是代码。我仍然得到校验和错误

<?php
function xxx_config() {

    $configarray = array(
     "FriendlyName" => array("Type" => "System", "Value"=>"XXX"),
     "alias" => array("FriendlyName" => "Merchant ID", "Type" => "text", "Size" => "20", ),
     "salt" => array("FriendlyName" => "SALT", "Type" => "text", "Size" => "20",),
     "mode" => array("FriendlyName" => "MODE", "Type" => "text", "Description" => "TEST or LIVE", ),

    );
    return $configarray;
}

function xxx_link($params) {


    # Gateway Specific Variables
    $key = $params['alias'];
    $gatewaymode = $params['mode'];
    $salt = $params['salt'];


    # Invoice Variables

    # System Variables
    $companyname = 'XXX';
    $systemurl = $params['systemurl'];
    $currency = $params['currency'];

        # Enter your code submit to the gateway...

$hashdata = ($key."|".$txnid."|".$amount."|".$productinfo."|".$firstname."|".$email."|"."|"."|"."|"."|"."|".$salt);

   $hash = hash("sha512", $hashdata);

您正在寻找（）函数。要创建sha512哈希，请按如下方式调用它：

hash('sha512', "the value to hash");

要了解您还可以使用哪些散列算法，请查看（）函数

，

s应该是文本字符吗？因此，您需要将变量与

|

和salt连接起来，并将结果字符串通过sha512？没那么难，你到底有什么问题？还有，SHA512！==“加密”。这是一个杂烩！Tx供您建议和更正。您的公式是正确的，但根据他们的公式，所有值（如txnid、name等）都应使用sha512算法进行加密或散列，即sha512（值），但上述公式不能做到这一点。请使用另一种方法进行帮助。是否要将每个值（txnid）与

串联，然后将其全部散列在一起，还是要将每个值散列，然后将其串联？每个值与|串联，然后散列。在上面的公式中，如果字段为空，则每个字段应包含一个PIP。比如，如果我在上面的公式中没有udf，那么我就用一根管子替换它，即总共11根管子。@user157053，我也有同样的问题。。。同样的公式。。。如果你得到最后的答案，也帮我
