RE: [flexcoders] Re: checksums (md5, sha1)
Probably impossible to do. The SWF is zipped and has a time-stamp in it so you'd have to get the compiler to commit the time stamp to the SWF at exactly the same time on every build, and the bytes of the time stamp change the compression table and thus the bits. You could add a step where you decompress the SWF and remove the timestamp and checksum the results.

I also questioned this when I first received the request, however I learned that the product I am working must pass a regulatory committee which requires that all binary files meet this requirement before being approved.

I'm not questioning your need, but as a newbie to Flex I am curious why you would do this, and if it's something I should be doing. Is it some sort of stability check?
