Ruby和PHP HMAC不一致 [英] Ruby and PHP HMACs not agreeing

问题描述

我正在尝试在Ruby中创建HMAC，然后在PHP中对其进行验证.

I'm trying to create an HMAC in Ruby and then verify it in PHP.

Ruby:

require 'openssl'
message = "A522EBF2-5083-484D-99D9-AA97CE49FC6C,1234567890,/api/comic/aWh62,GET"
key     = "3D2143BD-6F86-449F-992C-65ADC97B968B"
hash    = OpenSSL::HMAC.hexdigest('sha256', message, key)
p hash

PHP:

<?php
  $message = "A522EBF2-5083-484D-99D9-AA97CE49FC6C,1234567890,/api/comic/aWh62,GET";
  $key     = "3D2143BD-6F86-449F-992C-65ADC97B968B";
  $hash    = hash_hmac("sha256", $message, $key);
  var_dump($hash);
?>

对于Ruby，我得到:20e3f261b762e8371decdf6f42a5892b530254e666508e885c708c5b0bfc03d3

For the Ruby, I get: 20e3f261b762e8371decdf6f42a5892b530254e666508e885c708c5b0bfc03d3

对于PHP，我得到:e5f6995ba1496b2fb144329b2d1b3b23c8fa3211486e57bfaec5d993a1da9d15

For the PHP, I get: e5f6995ba1496b2fb144329b2d1b3b23c8fa3211486e57bfaec5d993a1da9d15

我和一些同事完全不知所措，任何帮助将不胜感激.

I and some colleagues are at a complete loss, any help would be greatly appreciated.

推荐答案

红宝石的OpenSSL::HMAC.hexdigest首先需要key，然后是message.

ruby's OpenSSL::HMAC.hexdigest expects first key and then message.

irb(main):002:0> OpenSSL::HMAC.hexdigest('sha256','3D2143BD-6F86-449F-992C-65ADC97B968B','A522EBF2-5083-484D-99D9-AA97CE49FC6C,1234567890,/api/comic/aWh62,GET')
=> "e5f6995ba1496b2fb144329b2d1b3b23c8fa3211486e57bfaec5d993a1da9d15"
