OK, turns out it is very simple to deal with compressed swf files like those generated by mxmlc. Just add these lines after line 5 in the script (where $sourceswf is initially set).

if( substr( $sourceswf, 0, 3 ) == "CWS" ) {
$endOfHeader = substr( $sourceswf, 3, 5 );
$swfMinusHeader = substr( $sourceswf, 8 );
$sourceswf = "FWS".$endOfHeader.gzuncompress( $swfMinusHeader );
}

This checks for the "compressed swf" header marker "CWS" and if present, uncompresses everything after the header. After that, the script proceeds as before.

Thanks!

I can't find a way to turn off compression for mxmlc. We are using Flex Builder, not Flash CS3. Any idea how to decompress the file so that this method can work?

[...] 3) Accessible to actionscript is rewriting of variables in the swf This is useful when root vars aren’t an option, and or license keys (e.g. encrypted tokens) need to be embedded into the swf. http://neurofuzzy.net/index.php?p=25 [...]

Yep, per string. You can indeed break it up, then patch it up with actionscript. I’ve just had to do this with for a program.

Hmm.. really? A 64k limit per string, or per SWF? If it’s the former, I figure if you need to go longer you could always split up your string and join it back together at runtime.

Yeah, the Captcha is tough… I just installed WP 2.01 with Authimage. I think there’s ways to tweak it. tough part comes when the contrast between background and letters is too low, or a letter drops off the bottom of the image. Is that an ‘L’ or an ‘I’?? :/

Nice tip, but also remember there’s a 64K limit on embedding a string this way.

(btw, i find your Captcha very tough, I’m on my fourth go)

I hope that MTASC will be able to solve this problem once and for all.
