JeremyCanada26 Posted July 9, 2010 Share Posted July 9, 2010 I am sending an image to my server and I'm using crc to check for errors in communication. I'd like to know if I should store the crc along with my image though as a means to check for duplicate images. There can potentially be millions of tiny images in the very long haul of my web app and I'd like to know if crc is unique enough for that or if maybe I should use md5 instead? Would two different images ever produce the exact same crc if you had like 50 million different images and calculated crc on all of them?
