Cryptographic checksum
WebI also have a basic understanding of how cryptographic hash functions work. They're more taxing to compute, produce a more randomized output, and generally have a larger output size than a checksum. And somehow they're designed to be secure. However, non-cryptographic functions are a mystery to me.
