Can you elaborate on the claim about SHA? If I'm not mistaken, all these cryptographic hashes have a 50% chance of flipping any one output bit upon changing a single input bit -- is there some hidden gotcha I'm unaware of?
- withinboredom 5y agoIt’s about random distribution. If you output an array of the key space as a bitmap, it should look like white noise. SHA doesn’t look like white noise. There are certain parts of the space it rarely goes with certain classes of inputs (numeric, usernames, etc) while murmur and md5 give that white noise look.
