Public Key:

The key that uses asymmetric-key encryption algorithms in public key encryption cryptography is known as public key.

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.
