I reported a bug with madSecurity a while back here:
http://forum.madshi.net/viewtopic.php?f=8&t=28726
Unfortunately the issue hasn't been fixed for over two months since the public report.
Privately, he has made it clear that he has no interest in fixing the bug unless he is getting paid for it, which makes it sound like the library is dead to me.
The self-professed "mad" author has moreover censored and edited the title of the post at his forum where I drew attention to the fact that he is no longer maintaining the library.
My company had sponsored the 64-bit version of madSecurity a while back, so we're definitely very taken aback that our investment was misguided.
Are there any alternatives to this library?
Moving forward, we will be moving our code off his platform, and would advise other developers to steer clear of madSecurity which has many subtle bugs and code that is very obtuse.
