Therefore sha256 hash of encryption key is validated against one which is stored
on server on poll creation.
This one is transfered as X-Croodle-Proof-Key-Knowledge HTTP HEADER.
Prevents an attacker of transmitting data with wrong encryption key, which
would cause decryption errors for legit users.
before it was done as computed properties of model
accessing encryption key in serializer is done via global application var.
this should be removed in long-term
There were some timezone issues especially concerning daylight saving time (DST).
We should not rely on timezone offset since this will change due to DST.
Instead determine the users timezone (using jsTimezoneDetect therefore) and
then using this via moment-timezone.
This commit changes poll model. It drops timezoneOffset and adds timezone as a new property.
It's not tested yet against polls created before without timezone property. This has to be done before merge.
Also we should consider using ember-moment template helpers instead of our own formatted-date helper.
