// secure hashing of passwords using bcrypt, needs PHP 5.3+
// see http://codahale.com/how-to-safely-store-a-password/

// salt for bcrypt needs to be 22 base64 characters (but just [./0-9A-Za-z]), see http://php.net/crypt
$salt = substr(strtr(base64_encode(openssl_random_pseudo_bytes(22)), '+', '.'), 0, 22);

// 2y is the bcrypt algorithm selector, see http://php.net/crypt
// 12 is the workload factor (around 300ms on my Core i7 machine), see http://php.net/crypt
