Question

What would be a best Class for base64 encryption/decryption in Action Script?

Answer 1

Adobe has two utils for this – Base64Encoder & Base64Decoder. Both are located in the mx.utils package. Although, I had to track them down here – encoder & decoder.

The usage would be something like:

var bmd:BitmapData = myBitmap.bitmapData;
var ba:ByteArray = bmd.getPixels(new Rectangle(0,0,bmd.width,bmd.height));
var b64:Base64Encoder = new Base64Encoder();
b64.encodeBytes(ba);
trace(b64.toString());

Similarly, ‘b64.encode’ would encode a String rather than a ByteArray.

Both the encoder and decoder add their respective results to an internal buffer. So, you just have to use ‘toString’ to return the current buffer.
