Zend encoding and security

I've been looking into the Zend encoder, for it's security benefits. However, it seems to me that it's really designed more to be a performance booster, rather than a security tool (ie: the security side is just more of a nice side-effect). I've searched through google/newsgroups/etc and haven't really seen any attacks against it's encoding methods. Does anyone have any thoughts about Zend encoding as a security mechanism? Is it really currently "ubreakable"? cheers, ly __________________________________ Do you Yahoo!? The New Yahoo! Search - Faster. Easier. Bingo. http://search.yahoo.com
