security - Is the iOS keychain encrypted without device passcode? -

-

up till believed ios keychain best way store usernames , passwords. however, came across this site states that:

"without passcode, data on device — including sensitive data stored in keychain — can read momentary access device"

i have gone through relevant sections in apples documentation on ios security , nothing explicitly states such?

is claim true or have misunderstood here?

the keychain implemented sqlite database stored on file system. there 1 database; the securityd daemon determines keychain items each process or app can access. keychain access apis result in calls daemon, queries app’s “keychain-access-groups,” “application-identifier,” , “applicationgroup” entitlements. rather limiting access single process, access groups allow keychain items shared between apps.

it means hacker can't access ur keychain data there no passcode. it's under control of apple's the securityd daemon. cant access data of keychain without the securityd daemon.

update:

maybe that's u want know: hacker vs keychain

routes - Laravel 4 Wildcard Routing to Different Controllers -

-
realizing i'm going take beating this, have several questions "best practices" when constructing laravel route. do laravel routes run "first come first serve" top bottom? if route found, pass control controller (or perform action) , terminate? i have part of application acts url shortner. so, route looks this: route::get('/{id}', array('as' => 'home.text', 'uses' => 'homecontroller@text'), function($id){ //make sure id exists before pushing controller. if (storage::where('shortcode','=', $id)->count() > 0) { // route found } }); how can improved? one, i'm not sure how pass processing on controller conditionally.. sort of controller::make() ..? 3) there better way in laravel check if record exists versus doing mode::where('column','=','value')->count() 4) have legacy urls http://url.com/?...
