I tried the function you posted but found during testing that a min value of 10 and max value of 11
would always result in a number of 10. I incremented the $range by 1 to overcome this.
Here's the modified code.
<?php
function crypto_rand($min, $max) {
$range = $max - $min;
if ($range == 0) return $min; // not so random...
$range++;
$length = (int) (log($range,2) / 8) + 1;
return $min + (hexdec(bin2hex(openssl_random_pseudo_bytes($length,$s))) % $range);
}
?>
