Let us generate SHA256 for the following two words: “Hackernoon” and “hackernoon”.
Generating SHA256 for any text is pretty easy with the help of online tools like SHA256 Hash Generator.
Above we have calculated SHA256 for the same word, but one of them is in sentence case.
If you observe just by Capitalizing “h” , there is a drastic change in the output.
Small changes in the input causing a drastic change in the output is known as “Avalanche Effect”.
It is very important to understand Avalanche effect since this property of SHA256 is one of the reasons why Satoshi Nakomoto has used it for the underlying cryptography of Bitcoin Blockchain.
In the next article we will have a deep dive into “Hashing Algorithms”. Stay tuned for the updates!
