WebFor hashing, prime numbers are used since they provide a better chance of creating unique values for a hash function. Hash functions (if you don’t know what hashing is please read this article) use modulus, and the use of composite numbers (i.e. non-prime) increases the probability of hash collisions (i.e. different inputs to result in the same hash). WebDefinition []. Fermat's little theorem states that if p is prime and a is coprime to p, then a p−1 − 1 is divisible by p.If a composite integer x is coprime to an integer a > 1 and x divides a …
