DB-side encryption via NHibernate -

-

we're looking encrypt field using db-side encryption via nhibernate (most examples we've come across app-side, not like). issue has been raised couple of times, no answers yet seems.

on sql server 2005, instance, , forgetting key-related issues now, means inserting encryptbykey(key_guid(mykey), myvaluetoencrypt) , selecting decryptbykey(myencryptedfield). property might string, whereas field has varbinary.

we've vaguely got somewhere - using upper() , lower() instead of encryption functions - combining paired properties, 1 mapped custom user type , other formula attribute.

however if has ideas on how in nicer way, we'd grateful few pointers :o)

unit testing - How to mock PreferenceManager in Android? -

-
i've written class using context , third party library , sharedpreferences preferencemanager . it's possible mock context , third party library can mocked using mocking framework, preferencemanager ? i have 2 methods: public void savestring(thirdpartyobject obj) { sharedpreferences apppreferences = preferencemanager.getdefaultsharedpreferences(mcontext); sharedpreferences.editor editor = apppreferences.edit(); editor.putstring(mcontext.getstring( r.string.preferences_string_name), obj.getstring()); editor.commit(); } and corresponding, loads preferences. it doesn't want mock instance of preferencemanager (which used in preferencefragment or preferenceactivity ). you want either: a mock sharedpreferences , in case can mock context#getsharedpreferences (which called preferencemanager#getdefaultsharedpreferences anyhow). you'll have make mock sharedpreferences.editor if preferences edited, above. know how moc...
