"WebA cryptographic hash function aims to guarantee a number of security properties. Most importantly that it's hard to find collisions or pre-images and that the output appears random. (There are a few more properties, and "hard" has well defined bounds in this context, but that's not important here.) " - Cryptographically secure meaning
