Generate HMAC Signature on PHP












-3















how do you apply the system below to php?



StringToSign = HTTPMethod+":"+RelativeUrl+":"+AccessToken+":"+

Lowercase(HexEncode(SHA-256(RequestBody)))+":"+Timestamp



Signature = HMAC-SHA256(apiSecret, StringToSign)


my script :



$encoderData = json_encode($bodyToHash, JSON_UNESCAPED_SLASHES);

$hash        = hash("sha256", $encoderData);

$stringToSign   = $Method. ":" .$url . ":" . $auth_token . ":" . $hash . ":" . $Timestamp;

$auth_signature = hash_hmac('sha256', $secret_key, $stringToSign,false);


Thank you,

I don't know what you mean but
You can try this;



<?php

    $stringToSign = 'abcd';

    $apiSecret = 'secretkey';



    $hashed = hash_hmac('sha256', $stringToSign, $apiSecret);

?>

This is working fine when I in the field "when running a task, use the following user account:" insert BUILTIN User Group (for example: Administrators or Users). But when I try it with the created Local User Group (example: TestGroup) it is not working. The Users in the TestGroup are the same as in the Administrators group. What could be the problem?
