You're right, that is my point.
I just did... using crc32 as an example. You can create your examples using another collision attackable hash like say, md5.
Thank you. I have learned with minimal pain.
Absolutely. Sharing our ideas, knowledge, and code, is what makes these communities what they are.
Thank-you for being receptive to new information - far too many people aren't these days.
And for everyone: I'm not saying X11 is broken. It's just no more secure then using a single hashing algorithm, IMO.
