Cryptographic Hash Function: An Elevated View Information is an
important commodity in the world of Electronic communication. To
achieve a secure communication between communicating parties,
the protection of authenticity and integrity of information is
necessary. Cryptographic hash functions play a central role in
cryptology. A cryptographic hash function takes an input of
arbitrary large size and returns a small fixed size hash value.
It satisfies three major cryptographic properties: preimage
resistance, second preimage resistance and collision resistance.
Due to its cryptographic properties hash function has become an
important cryptographic tool which is used to protect
information authenticity and integrity. This paper presents a
review of cryptographic hash functions.
