@Ain

This is what API docs says:

“The Adobe® AIR® runtime provides a persistent encrypted local store (ELS) for each AIR application installed on a user’s computer. This lets you save and retrieve data that is stored on the user’s local hard drive in an encrypted format that cannot easily be deciphered by other users. A separate encrypted local store is used for each AIR application, and each AIR application uses a separate encrypted local store for each user.

The ELS is appropriate for storing information that must be kept private from other users. It does not, however, protect the data from other processes run under the same user account. It is thus not appropriate for protecting secret application data, such as DRM or encryption keys.”

Correction: by the API docs, EncryptedLocalStore is not secure from other applications ran by the same user account.

@Elizabeth

Yes, you can use this approach :D

Great article, thanks.
The app I am designing, requires storing a report generated during a process, in a location of the users choice. Can we use the “store assets in files” to do this?
For example, after running a particular process, the user needs to store the error or exception report. Thanks in advance.

You can save data into .SOL cookie files too. :-)

i m makinhg a Adobe AiR application using flex builder 3.
can u plz solve my problem.

By: bart

Hi Avirag, what are you building?

I had similar problem, I ended up downloading the files from the Air application and store them in the Storage directory. Only tricky part is how you then get the swf files in the swfloaders, because that’s a securtity issue.

hi!!!!!
I already have 100 video files (.swf format) which I want to play in the player(made in Flex Builder3)
How can I store these videos files locally in SQLite and play them from there.
After that how to bundle my AIR application and database together to distribute my application to users.Actually,I want to make completely offline application for users having no net connection.

I will be thankful if u would give me code for this.

could it be that it just doesn’t work anymore in latest Air?

By: bart

bart — Sun, 07 Jun 2009 22:08:23 +0000

How do I load the swf back into the Air app?
I tried Swfloader.source = bytearray;
and Loader.LoadBytes(bytearray)

but I never get the loader.content object, it’s always null

I worked many hours on this problem, I need HELP !!

@dieyana

I don’t understand what you mean. The first topic my article is about how to save data in the local SQLite database (function writeData()).

By: dieyana

dieyana — Fri, 13 Mar 2009 06:54:14 +0000

hye…i’m interested in your article.but u didn’t mention on how an application can save data in the database.for example,when user click the ‘save’ button,all the data in that application can be saved into the database.

can you show that.

@Nils

We have solutions for DRM (based on FMS servers). however, you could use for your usecase storing the mp3 files inside of encrypted local database.

You need to protect only the transfer from server to the client.

Hello Mihai !

Have you had any experience on local caching of encrypted files ? For instance a MP3 file that you want to cache locally, but not allow the user to “steal” the file. Are there methods to encrypt mediafiles and leave them unusable to any other application than the Air app that stored the file ?

Thanks !

I don’t have one right now. But there is no difference between using this services in Flex web app, or in a Flex AIR app.

Actually you can use the example from this post, and change only the type of project you create. Instead of Flex with PHP, AIR with PHP. It should work without any changes.

Good luck!

The same way you do in a Flex app in web browser, you do in an AIR app.

I have already done in HTTP Service,Remote Object and Webservice in Flex.but how it is done in done in AIR Application.

thanks.

@Arun Patel

Send the data back to server. You can use HTTPService (REST services), RemoteObject, or WebService.
