WebJan 26, 2024 · Hashing means using some function or algorithm to map object data to some representative integer value. This so-called hash code (or simply hash) can then be used as a way to narrow down our search when looking for the item in the map. Generally, these hash codes are used to generate an index, at which the value is stored. WebMar 22, 2024 · Here's what I would do: pick a 64-bit number x that you want to commit. Make sure you can't factor it (it might be prime, but verifying primality is going to be tedious by hand). Then choose another, larger, 64-bit number y that is also hard to factor by hand. Now compute p = x y (easy) and send p to your buddy.
