security - Ensuring an iOS 4 app only runs if device meets certain password criteria -

-

our (internally distributed) ios app relies on ios 4.2's encryption secure sensitive data.

however, works satisfactory if user using system-wide password.

i understand can enforced installing configuration profile on ios devices configuring rules password.

since installation of profile optional our users, how can make sure our app works if profile installed, or alternatively, if password regulations met?

(we not concerned jailbreaks , related cracks our software, ability test config profile or other criteria inside our own code sufficient.)

what can do, create (self-signed) ssl certificate , add signing authority configuration profile. then, within app can attempt verify certificate. verification work if trust signing authority, happens if have configuration profile has been installed.

you can read more process here if wish: http://blog.slaunchaman.com/2011/12/01/enforcing-ios-security-settings-in-third-party-applications/

note: may not acceptable submission app store.

c# - Is it possible to remove an existing registration from Autofac container builder? -

something along lines: builder.registertype<mytype>().as<itype>(); builder.registertype<mytype2>().as<itype>(); builder.deregistertype<mytype>().as<itype>() var container = builder.build(); var types = container.resolve<ienumerable<itype>>(); assert.istrue(types.count == 1); assert.istrue(types[0].gettype == typeof(mytype2)); scenario: go through bunch of assemblies , go register types want make sure have 1 implementation of given type. need before create container. track on own nice if autofac me bit. this cannot done directly using containerbuilder , unless start on new one. mind you, having first built container should able construct new container filtering away unwanted types , reusing registrations first container. this: ... var container = builder.build(); builder = new containerbuilder(); var components = container.componentregistry.registrations .where(cr => cr.activator.limittype != typ

php - Mysql PK and FK char(36) vs int(10) -

-
i have read mysql can handle indexes , searches better if tables keys integers rather char(36) uuid's. is worth converting int(10)? note: use 1 server , have have plans use multiple databases concurrently therefore removing 1 of big reasons using uuid. our tables innodb if makes difference. thanks in advance. usually rdbms can handle integer keys pk more efficient, other datatypes. reason how build index column, yes: long dont require string (or other typed) keys, should use integers. however: char(36) , int(10) far away being equal, because int(10) much smaller, char(36). dont know, if require many different keys, should keep in mind. update, complete last paragraph: int(10) 32-bit, char(36) 36 - ^byte^ (= 288-bit). not mean, int consumes less space, means, char(36) has 4 times more different keys.
