Cryptographic hash function
A cryptographic hash function (CHF) is a hash algorithm (a map of an arbitrary binary string to a binary string with a fixed size of n {\displaystyle n} bits) that has special properties desirable for cryptographic applications. Hashing is a one-directional mathematical operation which is quick to calculate, yet hard to reverse. Common uses include password storage and digital signatures. Even a small change in the input results in a very different hash, meaning that it functions as an efficient and consistent way to check if two copies of data or software match. Typically, the operation works on a block of input data; the hash output is then hashed with the next block, creating a new hash reflecting everything to that point; this action is repeated until the hash reflects everything through the final block. More technically: the probability of a particular n {\displaystyle n} -bit output result...
