  - 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.
