But let’s be real hereit can get pretty boring to read through dry documentation all day long. So why not spice things up a bit?

First off, hashing algorithms. If you’re new to this game, hashing is basically taking an input and turning it into a fixed-size output that can be used for various purposes like data integrity or password storage. Rust has several libraries for hashing, but the most popular one by far is `rustcrypto`.

Now, let me tell you about `rustcrypto`’s hash functions. They have this thing called “digest” which sounds fancy and all, but really it just means that they take your input and spit out a fixed-size output. And the best part? You can choose from over 10 different digest algorithms!

`rustcrypto` also has this thing called “hash” which is basically like a supercharged version of digest. With hash, you get all the benefits of digest plus some extra features that are useful for certain applications. For example, if you want to verify data integrity in real-time, hash can help you do that without having to store any additional information.

Now cryptographic algorithms. If hashing is like a one-way street, then encryption and decryption are more like a two-way street (or maybe even a highway). Rust has several libraries for these as well, but the most popular one by far is `ring`.

`Ring` offers a variety of cryptographic algorithms that you can use to encrypt your data. But be warnedthese algorithms are not for the faint of heart! They involve things like symmetric and asymmetric encryption, key management, and message authentication codes (MACs). And if you’re really feeling adventurous, you can even try out some advanced techniques like perfect forward secrecy or authenticated cipher modes.

But let me tell you somethingif you want to use `ring` for anything other than a hobby project, be prepared to spend hours reading through documentation and testing your code. And if you’re not careful, you might even end up with some security vulnerabilities that could compromise the privacy of your users!
