Hello everyone,

I'm trying to connect OpenProject to a PHP-Script, which works fine, but I can't generate a correct hmac-hash to verify OpenProject as sender.

This is my code:

$rawdata = file_get_contents("php://input");
$hash = hash_hmac("sha1", $rawdata, "test123");

Quite simple, my keys are the same (checked that like 1000 times), but the hashes differ.

The Request's header states: 3ce4bf27a90fd773cf9b2fd1f0cd4f6c850a9263
but my hash is actually 6396bacdb89cca760fb102f4ed2b081f31ca8e5a

What am I doing wrong? Is the raw body somehow encoded that needs decoding first, or something else that I missed?

Thanks for your help
Thomas
