Adobe Flash Builder - using EncryptionKeyGenerator

Question

Hi there!
I'm desperately trying to create a simple app that would generate Encryption key using standard adobe.air.crypto package for my SQLite database file.
Purpose is to enter text password and as a result - get encryption key.
Here I found complete guide for it:
http://help.adobe.com/en_US/AIR/1.5/devappsflex/WSAD329515-CBF1-4658-8DD7-CAC9C354CE94.htm l
I created New Flex project in Flex Builder and posted in new MXML application the code from link above.
However while building app I experience difficulties:
Description

1046: Type was not found or was not a compile-time constant: EncryptionKeyGenerator.
Main.mxml
/B2B test/src
line 31

/B2B test/src
line 78
Flex Problem
1180: Call to a possibly undefined method EncryptionKeyGenerator.

line 31
Flex Problem
Can somebody help me?
Should I manually connect as3lib to my app? How?
I am a newbie to Flash Builder.
Maybe someone could compile this example app so that I could use the result?
Thank you in advance!

The crypto libraries work ok on the desktop but don't work in Android because some classes like MD5 for example don't run on the mobile version. I had the same problem running a SWF a webview. It used the MD5 and SHA1 classes that don't work in Flash Lite or even Flash Player 11 for Android.
You could try posting what you need to encrypt to a server and use the response. I suggest you use a PHP-specific encryption library. If you really really want to use the crypto library. You could publish a SWF file that does the encoding then saves the output to a web server file then have your app read that file but it's slow.
