This is the error returned when I try to access a blob in storage:

Code: AuthenticationFailed Message: Server failed to authenticate the request. Make sure the value of Authorization header is formed correctly including the signature. AuthenticationErrorDetail: Signature did not match. String to sign used was xxstorageaccount rwdlac b sco 2017-08-17T21:29:24Z 2017-08-17T21:34:24Z https 2017-04-17

Here's my code:

$storageAccount = config('azure.storage.account');

$start = new \DateTime();     
$end = (new \DateTime())->modify('+5 minutes');
$start = $start->format('Y-m-d\TH:i:s\Z');
$end = $end->format('Y-m-d\TH:i:s\Z');

$toSign = $storageAccount . "
";
$toSign .= "rwdlac" . "
";
$toSign .= "b" . "
";
$toSign .= "sco" . "
";
$toSign .= $start . "
";
$toSign .= $end . "
"; 
$toSign .= "
";
$toSign .= "https" . "
";
$toSign .= "2017-04-17" . "
";

$signature = rawurlencode(base64_encode(hash_hmac('sha256', $toSign, $sasKeyValue, TRUE))); 
$token = "?sv=2017-04-17&ss=b&srt=sco&sp=rwdlac&se=" . $end . "&st=" . $start . "&spr=https&sig=" . $signature;

return $uri . $token;
