PHP getServerNonce Examples

Example #1

File: login.php Project: evandentremont/proof-of-work-login

function getValidServerNonces($specific = false)
{
    $tmp = array();
    $timestamp = time();
    $timestamp = $timestamp - $timestamp % NONCE_CHANGE;
    for ($i = 0; $i < (int) NONCE_LIFE; $i += NONCE_CHANGE) {
        $tmp[$timestamp] = getServerNonce($timestamp);
        if ($specific !== false && $specific == $tmp[$timestamp]) {
            return true;
            break;
        }
        $timestamp -= NONCE_CHANGE;
    }
    unset($timestamp);
    return $tmp;
}

Example #2

File: login.php Project: jsavoie/proof-of-work-login

function getValidServerNonces($specific = false)
{
    $tmp = array();
    $timestamp = time();
    // count backwards and check each interval
    for ($i = 0; $i < NONCE_LIFE; $i += NONCE_CHANGE) {
        $tmp[$timestamp] = getServerNonce($timestamp);
        if ($specific !== false && hash_equals($tmp[$timestamp], $specific)) {
            return true;
        }
        $timestamp -= NONCE_CHANGE;
    }
    unset($timestamp);
    // return false if asked to validate a specific server nonce
    if ($specific !== false) {
        return false;
    }
    return $tmp;
}
