如何發佈sha512加密數據

Question

我需要幫助我的PHP腳本。我需要以加密方式發佈特定字段，如invoiceid，firstname，email等。校驗公式爲

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

我需要通過sha512發佈上述變量。我無法做到這一點。請幫助。我是一名學習者，而且我不擅長PHP。

這是代碼。我仍然得到校驗錯誤。

<?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 
    $txnid = $params['invoiceid']; 
    $productinfo = $params["description"]; 
    $amount = $params['amount']; # Format: ##.## 
    $currency = $params['currency']; # Currency Code 

    # Client Variables 
    $firstname = $params['clientdetails']['firstname']; 
    $lastname = $params['clientdetails']['lastname']; 
    $email = $params['clientdetails']['email']; 
    $address1 = $params['clientdetails']['address1']; 
    $address2 = $params['clientdetails']['address2']; 
    $city = $params['clientdetails']['city']; 
    $state = $params['clientdetails']['state']; 
    $postcode = $params['clientdetails']['postcode']; 
    $country = $params['clientdetails']['country']; 
    $phone = $params['clientdetails']['phonenumber']; 

    # 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); 

$code = '<form method="post" action="https://secure.xxx.xxx" name="frmTransaction" id="frmTransaction" onSubmit="return validate()">

<input type="hidden" name="Hash" value="'.$hash.'"/> 
<input type="submit" value="Pay Now" />

return $code;

Answer 1

該hash（）函數是你在找什麼。要創建SHA512哈希如下稱之爲：

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

看到哈希算法你還能用什麼來看看在hash_algos（）函數
