Opinionated interface for many key/value repositories:

I am kind of tired of having to do small changes when I move from Dictionary, to Redis, to Shelve or whatever key/value storage I am using. This is an interface heavily inspired by builtin shelve module to make all those mapping repositories behave the same way:

• Get item: storage['key'] returns the value associated to 'key' and raises a KeyError if 'key' is not defined. storage.get('key') behaves the same way but returns default() when 'key' is not defined.

• Set item: storage['key'] = val associates val to 'key' and raises a KeyError if 'key' already has a value associated. storage.set('key', val) behaves the same way but overwrites association if it already exists.

• Delete item: del storage['key'] deletes 'key' and raises a KeyError if 'key' is not defined. storage.delete('key') behaves the same way but does nothing when 'key' is not defined.

• Expiration: You can define expire_seconds parameter to make your associations expire. Expiration time is refreshed every time you access a key.

• Encryption: You can define a passphrase parameter to encrypt your values using symmetric encryption.
