Hash Function
Hash Function is a mathematical function that converts a large, variably-sized data into a small datum. There are many hash function algorithms(1) MD5
(2) SHA-1 , SHA-2 SHA-3 (Secure Hash Algorithm)

MD5 Algorithm
An algorithm created in 1991 by Professor Ronald Rivest that is used
to create digital signatures. It is intended
for use with 32 bit machines and is safer than the MD4 algorithm, which has
been broken. MD5 is a one-way hash function, meaning that it takes a message and converts
it into a fixed string of digits, also called a message digest.
