Safe is a hybrid mobile app that helps to keep your photos safe. The stored photos are encrypted using AES-256 algorithm. Safe supports iOS and Android platforms. To know how I built Safe step by step please take a look at this series.
Safe is created in the aim to guide developers how to design and develop a hybrid mobile app using client-side technologies.
Safe is built using Cordova and with plethora of client-side technologies like Backbone, Underscore, RequireJs and Handlebars. Ratchet is used to give the look and feel.
Setting up the machine
You've to install Node, Grunt, Bower and Cordova. To configure the machine for iOS and Android development please go through the cordova platform docs.
Once you've installed the necessary tools and downloaded the source-code, you might have to modify couple of configuration properties in the grunt file (Gruntfile.js).
supported property is an array that is used to specify the platforms that you've configured in your machine.
If you are using Windows, then you can configure only for the android platform and you should update the
supported property to
At a time you can run Grunt commands for a single platform. For example you cannot build the source-code for both the platforms through a single command. You've to pass the platform parameter along with the Grunt commands. If you don't pass the parameter then what you've specified in the
platform property is used.
Install node modules and bower components
Once your machine is setup, you should run the following commands from the terminal.
This will install all the required node modules locally for the project.
This will install all the required bower components locally for the project.
Once you installed all the necessary components, you should run the below grunt command.
This will create the cordova project and install the supported platforms and the needed plugins.
Assuming you've configured for both the platforms and the default platform is 'ios'. Following are the other important grunt commands you should know.
|grunt||Start a web server and run the app for iOS in browser|
|grunt emulate||Run the app in iOS emulator|
|grunt deploy||Deploy the app in iOS device|
|grunt --platform=android||Start a web server and run the app for Android in browser|
|grunt emulate --platform=android||Run the app in Android emulator|
|grunt deploy --platform=android||Deploy the app in Android device|
|grunt tests||Run the Jasmine unit tests|
The key that is used to encrypt the credential is stored in the settings file which exist under src/js. You SHOULD update the
encDecKey and set a complex base64 string to it.
While testing in couple of Nexus devices I noticed the encryption is taking too much time. I tested in a brand new Moto E device and it was blazing fast. If you are facing too much slowness then you could turn off encryption by overriding the
encrypt property in settings file to false, which I don't recommend!
Safe supports currently iOS and Android platforms. If you are interested to extend the support to other platforms please contact me. I'll be so glad to help out.
