If the checksums are equal, we can claim that the files are identical, considering the fact that getting the same hash for two different files is almost impossible.Īnd many websites provide hashes of the files at the download pages, especially when the files are located on different servers. In this way, if we generate two checksums for two files, we can declare that the two files aren’t duplicates if the checksums are different. That is how all the data is verified in TCP/IP protocols. The checksum (from a known hash function) of received data can be compared with the checksum provided by the sender to verify the purity of the segment. These checksums are used to verify if a segment of data has been modified. That means, getting the same hash for different inputs is nearly impossible in practice. This hash function should have a minimum rate of collisions such that the hashes for different inputs are almost unique. The checksum is a small sized datum, generated by applying a hash function on a large chunk of data. While hashing is used in many applications such as hash-tables (data structure), compression and encryption, it is also used to generate checksums of files, network data and many other input types. So, it is always good to have a better hash function with fewer collisions, which makes it difficult to find two inputs which give the same output. In the above-mentioned hash function, you can see that there is a significant probability of getting the same hash (collision) for two different inputs. We can define a hash function to get the hash of the numbers between 0 to 9999. The main properties of a hash function are: The output is usually known as the hash of the input. These input objects can vary from numbers and strings (text) to large byte streams (files or network data). Hash is a mathematical function which takes objects as inputs and produces as output a number or a string. There are multiple ways to do so, including Hash Comparison which is turning out to be a highly popular and reliable.
So, how can we easily compare two files in such manner that is credible yet not at all laborious?
Checking each byte over the Internet would take years to accomplish and also eat up a significant portion of your Internet bandwidth. Let’s imagine that we are downloading a large file over the Internet and we need to make sure that the file was not modified by a third-party in the midst of the transmission, which may cause a man-in-the-middle attack.

An easy way to remove duplicates would be to utilize an all-purpose duplicate cleaner such as the Clone Files Checker. Imagine comparing two gigantic files to check whether they are duplicates, the time and the effort you need to spare for undertaking such a task is probably enough to simply make you give up. Even though this is simple for smaller files, performing a one-to-one (byte-to-byte) comparison for large files is a massively time-consuming task. To check if two files are duplicates of each other, we should do a one-to-one check for the suspect files. Finding duplicate files is a hectic task when you have millions of files spread all over your computer.
