Xamarin.Forms, Akavache and I: ensuring protection of sensitive data

Recap

Some of you might remember my posts about encryption for Android, iOS and Windows 10. If not, take a look here:

Xamarin.Forms, Akavache and I: storing, retrieving and deleting data

I just blogged: #Xamarin.Forms, #Akavache and I: storing, retrieving and deleting data

Caching always has the same job: provide data that is frequently used in very little time. As I mentioned in my first post of this series, Akavache is my first choice because it is fast. It also provides a very easy way to interact with it (once one gets used to Reactive Extensions). The code I am showing here is living in the Forms project, but can also be called from the platform projects…

Xamarin.Forms, Akavache and I: Initial setup (new series)

I just blogged: #Xamarin.Forms, #Akavache and I: Initial setup (new series)

Caching is never a trivial task. Sometimes, we can use built-in storages, but more often, these take quite some time when we are storing a large amount of data (eg. large datasets or large json strings). I tried quite a few approaches, including:

built-in storage

self handled files

plugins that use a one or all of the above

Akavache (which uses SQLite under the hood)

Why Akavache wins

Well, the…

Akavache: Key-Value Store for Your Desktop Apps

Akavache[https://github.com/github/Akavache]

An Asynchronous Key-Value Store for Native Applications

Akavache is an asynchronous, persistent key-value cache created for writing native desktop and mobile applications in C#. Think of it like memcached for desktop apps.

What does that mean?

Downloading and caching remote data from the internet while still keeping the UI responsive is a task that nearly every modern native application needs to do. However, many applications that don't take the consideration of caching into the design from the start often end up with inconsistent, duplicated code for caching different types of objects.

Akavache is a library that makes common app patterns easy, and unifies caching of different object types (i.e. HTTP responses vs. JSON objects vs. images).

It's built on a core key-value byte array store (conceptually similar to a Dictionary<string, byte[]>), and on top of that store, extensions are added to support:

Arbitrary objects via JSON

HTTP Requests

Fetching and loading Images

Securely storing User Credentials
