Hash Function: Any function that can be used to map data of arbitrary size to data of a fixed size is called a hash function. Hash functions provide message integrity as it is computationally infeasible to find any two messages with the same hash. Digital Signature: Public-key primitives of message authentication are called digital signatures.
