I built this over at https://www.hypermind.xyz/sha-256-hash-generator/ to demonstrate how SHA256 really works. It’s pretty cool. Take a play around and see for yourself.
What is SHA-256
An SHA-256 is an algorithm created by the NSA to generate a 256 bit (32 byte) hash for a given text.
Hashing is different from encryption, in that encrypted data can be decrypted. Hashing on the other hand is a one-way function. Any like for like body of text will hash the same, no matter how long or short the text.
Add your sentence or text into the textbox here. The data will have the same hash no matter how many times you try to run the sha-256 algorithm. This is what makes hashing secure — it is easy to identify when data has been compromised and also easy to completely secure the data by adding a nonce and other unique text in the data to create a hash which can’t be reverse-engineered.
