Amulet, short text poems that SHA-256 into a hash with four or more 8s in a row
- ChrisGranger 6y agoI realize it would be an incredible long-shot, but I wonder if anyone will ever find an amulet that also has four eights in a different hash function.
- schoen 6y agoFour eights in SHA-256 plus four eights in (say) MD5 is just as likely as eight eights in SHA-256, at least if each hash function is truly a good approximation of a pseudo-random function. (In fact, since the definition didn't specify where the eights are, and they can be anywhere in the output, I think four eights in each of two different hash functions is more likely, because there's more total output digits in which to look for them.) Edit: If you don't specify the other hash function in advance, it's even more likely, because you can first find your SHA-256 amulet and then keep searching for a hash function in which it is also an amulet, where you might have a dozen or two potential choices that amulet-viewers might find interesting or impressive, each of which gives a new roughly independent space of possible amuletness.
