    - Cryptographic hash function is a hash function that recreates the input data from its hash value.

    - Cryptographic hash functions have many information security applications.

    - They can also be used to detect duplicate data or uniquely identify files and to detect data corruption.

    - Cryptographic hash function return fixed size bit string when it takes an arbitrary block of data.

    - It processes an arbitrary length message into a fixed-length output. This can be achieved by breaking the input up into a series of equal sized blocks and operating them in sequence using a one-way compression function.
