cryptographic hashes are different from image fingerprints

• bo1024 5y ago
  That's true, one way to put it is that traditionally non-cryptographic hashes are supposed to prevent accidental collisions, while cryptographic ones should prevent even collisions on purpose. But hashing is used in many places that could be vulnerable to an attack, so I think the distinction is blurry. People used MD5 for lots of things but are moving away for this reason, even though they're not in cryptographic settings.
