I've spent several hours reading through many posts already trying to get this to work and am still having issues with it. I'm trying to use the protectedpdf api which requires a three step process to login and receive an auth token, involving the hmac_sha1 hashing algorithm.
I'm making use of the hmac_hash() function in php so the code is simply:
$accessKey = "test";
$dataString = strtolower((string)$clientNonce.(string)$serverNonce.$accesskey);
$clientHash = strtoupper(hash_hmac('sha1', $dataString, $accessKey));
Where ClientNonce and ServerNonce are uuids like 30df805c-27d6-4df1-b482-48b685cc8f54
For a sample set of Client and Server Nonces, the built-in php function returns:
C39B753E50DB06DF3DE8E41C682FA8151B49ECBD and i get an authentication error in response to the login attempt.
Using the free formatter hmac generator online tool the same input yields:
7f48c3018c0e53a0b64a60bb7809c7a20a80c9a2
I would greatly appreciate any help - thanks!!!
