Base64 Encoding for ActionScript 3/Flex 2.0

I updated this Base64 Encoder to work with ActionScript 3 for Flex 2.0 Beta 3.

New version:  Base64.zip

Also, there’s this version, which is binary data oriented:

Note that I’ve only done rudimentary testing with these.   It may not work perfectly.

  1. Cool. Thanks!

    One question, though: doesn’t AS 3.0 have a native Base64 encoder? :D

  2. Heh. I felt really stupid for a while, but I just checked the Actionscript 3.0 docs at the Adobe site, including the corelib documentation, and I can’t find anything that indicates native Base64 support in AS3.

  3. I’ve officially lost my marbles. I definitely saw that - it was there. Beta 1 or 2. Or alpha.

    I have no idea where it’s gone.

    So, ignore my question. Blame it on the lack of marbles. :)

  4. Actually, I have discovered by looking at CoreLib that it is there in the code - (mx.util.Base64Encoder), but it is not in the documentation.

  5. Like I said, I know I’d seen it…and there were docs for it at one point in time, but they’re very gone now. Oh well.

  7. How Can I display that Image on webpage. Can I bind to Image control? After Decoding?

  8. Sorry, what do you mean?

  9. I used the Base64 encoder provided in the article, but the encoded string is not divisible by 4. All Base64 encoded strings should be divisible by 4 so this does not work when you encode and call a Java webservice, since it will complain that “java.lang.IllegalArgumentException: Length of Base64 encoded input string is not a multiple of 4.”

  10. Great, but I have a question. Why it is encoding (or decoding) the non-english letters wrong.
    I input this string: “Mókamaki mizériája” and I recive this one after encoding and decoding: “Mkamaki mizrija”? I lost all my “special” characters…

  11. If you’re just base encoding strings, you can easily use Flex’s existing classes. Look to the encode, and flush methods. I mention it on my blog, but found the classes thanks to you !!!
