What is a cryptographic hash function?
A cryptographic hash functions is a mathematical formula that helps you convert a given value to another value that is irreversible.
In a hash functions you can feed any size of information but you still get a same length value.
The value that you get after processing a set of data through a hash function is called a hash value or sometimes is commonly called a message digest.
The process of transforming a given set of data to a specific hash value is called hashing the data.
The resulting value after hashing is much smaller compared to the data that passed through the function. This makes hash functions to act like kind of compression functions.
 Read: The complete list of ciphers.
The resulting value after hashing the data is called a digest.
One advantage of hash functions over normal ciphers techniques is that they as super fast and the resulting output is smaller too.
Hash are supposed to be one way function and irreversible.
Also a hash function should not result to the same value for two different pieces of information.
When two different pieces of data result to the same hash value, in that case collision has occurred and the function is not fit for use.
