`Hey,

Note: Brother if you have any queries related the answer please do comment. I would be very happy to resolve all your queries.

In cooking, to hash something means to chop it and then mix it. It’s from this we get “hash browns” — the shredded-and-fried potato king of an English breakfast. A hash function is where a computer takes an input of any length and content (e.g. letters, numbers, and symbols) and uses a mathematical formula to chop it, mix it up, and produce an output of a specific length. This is how we can take all 14 lines in Shakespeare’s sonnet, or the 31 verses in Chapter 1 of Genesis, and produce an output of only 32 characters.

We can create hashes of nearly any digital content: a document, an image, a song, anything. It may be easier to understand when you remember that any digital content is, at its lowest level, just a string of zeros and ones. Everything can be represented in binary: “hello!” in UTF-8 binary is 01001000 01100101 01101100 01101100 01101111 00100001. It’s this binary code that a hash function is scrambling.
