PHP hash_hmac 无法得到与 vb.net 结果 HMACSHA 相同的结果

Question

VB.net 代码：

Function HMACSHA(ByVal Key As String, ByVal Value As String)

   Dim objHMAC As New HMACSHA1(Encoding.ASCII.GetBytes(Key))

   HMACSHA_Encrypt = (objHMAC.ComputeHash(Encoding.ASCII.GetBytes(Value)))

End Function

例子

Key         e.g. “RHBNow”
Value       e.g. “7090982.885183” based on custom hash algorithms
Hash value  e.g. bcf370bcbb6248c4d718ec17e5c6982477744f6a

PHP：

$ha1='RHBNow';

$ha2=7090982.885183;

$binarySignature = base64_encode(hash_hmac('sha1',$ha1,$ha2, true));

$urlSafeSignature = urlencode($binarySignature);

结果：

PS7%2FPqt95CtEEGeNsNOV1y%2FEaQ4%3D

无法得到与 vb.net 相同的结果。

Answer 1

请尝试以下方法：

<?php
$ha1 = "RHBNow";
$ha2 = "7090982.885183";
echo $hash = hash_hmac('sha1', $ha2, $ha1);
?>

谢谢。
