Introduction to hashing

Have you ever used dictionaries or maps in your language of choice, or have you ever met a mysterious MD5 code while downloading a file from a server? Maybe you are a programmer, and using Git to manage your code you ended up dealing with strange numbers called SHA1, and surely you heard at least a couple of times the term cache, which probably needed to be emptied in your browser.

What do all these concept have in common?

In this post I want to introduce you to the concept of hashing, which is one of the basic topics a good programmer shall know. Hashes are such an important topic in computer science that lacking knowledge in this field means being confused about a wide range of other subjects, like cryptography and security. Just to name some of the players you could be interested in your future career as a programmer: data structures, Bitcoin and blockchains, HTTPS. All these topics have hashing as one of their building blocks. As you can see, it is worth mastering the concept.
