I am building an application in Flex, wherein I need to encrypt user id and password using the SHA1 alogorithm. I have not come across any standard Flex library which allows me to do this. Does anyone know how to achieve this in Flex?
View 1 RepliesI've tried a couple different hash classes for as3. Right now I'm using the com.adobe.crypto package from [URL] What I need is a way to return the raw data as opposed the the hex converted string, similar the the way python's hashlib functions have a digest() and hexdigest() method. In python the code would be
...
single = sha1('some text').digest()
double = sha1(single).hexdigest()
...
In as3 using the following code returns a different hash because the return from the first hash is converted to hex before being hashed again.
...
SHA1.hash(SHA1.hash('some text'));

View 1 RepliesI am writing a Flex application for use on a private intranet with no external Internet access. I want to use Google's 3D Maps Flex API, but it must be connected to the internet to download map tiles on demand.
Is there a way to locally cache the 3D map tiles and data so that I can run this app without an internet connection? And if not, is there a 3D GIS that supports Flex integration and allows for a local map cache?

View 1 RepliesI have a function that restores all of the default settings of my application. This process can take a bit of time, so I would like to implement a "Please wait..." modal popup to let the user know that everything is alright and the program hasn't frozen. Once the function completes its task, I'd like for it to remove the message, and resume normal behavior.

View 1 RepliesI've written a Flash (Flex) client connecting to a back-end server to exchange data. I've also written my server from scratch, and it serves two purposes:
(1) Web (HTTP) Server- By default listens on port 80
(2) Socket/Application- Server - By default listens on port 443
Just FYI, both servers run in the same process space, for convenience reasons. They are not expected to handle massive loads, so I'm fine with that. As soon as the Flash client is served to the browser from the HTTP socket, the client attempts to open an XMLSocket to the Socket/Application server. I now want to implement HTTP tunneling, so that my client can connect to the Application server even if the user is behind a firewall. I do not want any external servers involved (proxies etc.) - simply use the servers I already have.
My questions:
(1) Is it better to use port 443 for that? (does it better fool firewalls?)
(2) As far as I can see, what I am required to do, is just ensure that my actual application data is simply encapsulated in an HTTP structure (preceded by a dummy HTTP header), both from the client and server sides. Is that so or am I missing anything here?
(3) Do I need to keep hiding/encapsulating my data every message I send through the socket, or can I just encapsulate the first message when opening the connection?
I am considering creating a website with the complexity of Facebook that should be able to scale into the millions of users. My question is: Is there any reason not to use Adobe Flex for such large project apart from the obvious point of requiring everyone to have Flash installed and not having to rely on Adobe? In my view Adobe Flex would reduce the server load for Facebook, because more of the work could me done on the client side.
View 7 RepliesI have a List component from which I'd like to be able to remove items using drag & drop, but without having a specific target. If you use the mac, the behaviour I'm looking for is something like what the Dock uses; when you drag something out of the bounds of the control it should get an icon that indicates that it'll be deleted (OSX uses a cloud or something?) and then if you release it it will be removed from the list.

View 1 Replieswe have one application where we are pulling some confidential information from one of the product design tools. So we have used HTTPS as the channel and also we are encrypting the Request Parameters and Some data before we sent it to Web Services.Everything seems OK.But when we gave the application for Security auditing they found we have hard coded the encryption key in source code. They have used Sothink SWF Decompiler to look into my SWF file. They caught the key and raised concern over it.
We have developed this application using Flex 3(SDK 3.4). Is there any best way to use Secret key without being hard coded in source code. If anybody come across this kind of problem, please let me know. use the secret keys in SourceCode without being Hard coded.
Here is my sample code:
var currentResult:String = "";
var strDataToEncrypt:String = "";
var kdata:ByteArray;

Currently, i have been compiling my applications with FD/CS3 and want to make the switch to the flex compiler. One of the main things i want to experiment with the flex compiler is using Macros in AS3. For instance, say i have some extremely expensive operation that i wish to carry out:
private function Main():void
{
extremelyExpensiveOperation(params);
}
but i want to avoid the cost of a function lookup. So instead of using a function lookup I do something like
private function Main():void
{
<macro expandExtremelyExpensiveOperationHere(params)/>
}
obviously the syntax doesn't have to look exactly like that, but the macro gets expanded before compilation thus avoiding function lookup.
The scribd fullscreen mode is pretty neat (example: http:url...). The advantage (for RIAs specifically) is that it doesn't (almost) completely disable the keyboard the way the 'default' fullscreen mode in Flash Player does. Seems to also work when embedded.

Does anyone know of a simple way to implement a DividedBox layout similar to flex, but done through Flash/as3 ?
I would think there would be a library out there for that already, or some resources, but I'm having a hard time googling for it, as it;s either Flex or unrelated content I keep finding.
EDIT just came across yahoo's astra library (example)
