We will take two files from the user and then compute their hash code and compare them to see weather they are same? If hash code is same means files are exactly same else they are different. Here I am showing what we are trying to make Let's implement the hash comparison in our code. Hence we can immediately know that file content is different. If we change even 1 bit in the files the hash code calculated after the changes is totally different. Hash is actually 20 byte code that is computed by Hash algorithm. But in some cases comparing through hash algorithm is more efficient method.
#Hashtab compare a file how to#
This article shows you how to compare two files using HashAlgorithm.We can compare files in many ways like byte by byte comparison.
