Might come in handy for you, they’re available for download here.

I included FLA’s for Flash8 and FlashCS3 for AS2 and AS3.
They show 2 TextInput components, one for an email address and one for a cell phone number.
The cell phone validation includes a “strip” function. Since people tend to enter their phone numbers in different ways, dots, blanks and slashes are removed from the input before validating the number.

AS2 Usage example:

import be.boulevart.as2.validation.Email;
import be.boulevart.as2.validation.GSM;

class be.boulevart.as2.playfield.Validation extends MovieClip
{
    // Elements on Stage
    private var check_btn:Button;
    private var email_ti, phone_ti:TextInput;
    private var emailOk:Boolean;
    private var gsmOk:Boolean;

    public function Validation() {}

    private function onLoad():Void
    {
        check_btn.addEventListener("click", Delegate.create(this, doValidation));
        email_ti.tabIndex   = 1;
        phone_ti.tabIndex   = 2;
        check_btn.tabIndex  = 3;
    }

    private function doValidation():Void
    {
        emailOk = Email.validate(email_ti.text);
        gsmOk = GSM.validate(phone_ti.text);

        if(!emailOk)
        {
            Alert.show("Invalid email address!", "Error", Alert.OK, this);
        } else {
            Alert.show("Email address is valid!", "You rock dude", Alert.OK, this);
        }

        if (!gsmOk)
        {
            Alert.show("Invalid cell phone number!", "Error", Alert.OK, this);
        }
        else
        {
            Alert.show("Cell phone number is valid!", "You rock dude", Alert.OK, this);
        }
    }
}

AS3 Usage example:

package be.boulevart.as3.playfield
{
    import be.boulevart.as3.validation.Email;
    import be.boulevart.as3.validation.GSM;
    import flash.display.MovieClip;
    import flash.events.*;

    public class Validation extends MovieClip
    {
        protected var emailOk:Boolean;
        protected var gsmOk:Boolean;

        public function Validation()
        {
            check_btn.addEventListener("click", doValidation);
            email_ti.tabIndex = 1;
            phone_ti.tabIndex = 2;
            check_btn.tabIndex = 3;
        }

        private function doValidation(evt:Event):void
        {
            emailOk = Email.validate(email_ti.text);
            gsmOk = GSM.validate(phone_ti.text);

            if(!emailOk)
            {
                trace("Invalid email address!");
                email_result.text = "Invalid email!";
            }
            else
            {
                trace("Email address is valid!");
                email_result.text = "Valid email!";
            }

            if (!gsmOk)
            {
                trace("Invalid cell phone number!");
                phone_result.text = "Invalid phone!";
            }
            else
            {
                trace("Cell phone number is valid!");
                phone_result.text = "Valid phone!";
            }
        }
    }
}

Enjoy! :-)

I’ve started off with the great encryption classes written for AS2 by meychi.com (currently offline), but felt there had to be a more user-friendly way of using them, so I got to work on it last night and think I’ve come up with a pretty elegant solution.

You can download the ZIP-archive to try it out for yourself.
Please note that this release is still early alpha and there’s probably alot of room for improvement, I’ll post updated copies for the files here regularly. There’s also still little documentation in the files and there aren’t any unit tests yet.
Inside the ZIP you’ll find an FLA for AS2 and one for AS3. The AS2 FLA comes in a Flash8 and a FlashCS3 flavour.
The FLA’s contain a single MovieClip with a linkage to their respective .as source files.

Inside the package be.boulevart.as2.security are the wrapper classes I wrote for the original AS2 implementation by meychi.
What this does is provide you with an elegant way of using any encryption type with just a single line of code:

e = new Encryption(EncryptionTypes.RC4(), str , this.theKey, null, null, null);

See what I did with the EncryptionTypes there?
Since AS2 nor AS3 provide Enum’s (like for instance C# does), the static class EncryptionTypes serves as a wrapper for the various AS2 encryption classes. It’s functions return an Object instance of the appropriate encryption class. So instead of importing all the encryption classes to your class and instantiating a new instance for each class, you just import be.boulevart.as2.security.* and call EncryptionTypes.<type_you_choose>();

Next, pass in the string you want to encrypt and (depending on the encryption type you choose) additional parameters.
Now you can just call e.encrypt to encrypt your string and e.decrypt to decrypt it.
Wasn’t that easy?

I also ported the originals by meychi to AS3.
Only GUID and LZW ain’t working in AS3 just yet.

Like I said, still early alpha, but nevertheless fun to play with :-)

Let me know what you think about it!
