What's Hashing For?

Yo, why even bother with hashing, right?

Hashing is basically like putting a lock on your vibe. 🔒 It’s there to make sure the deets are on point.

Since every hash is unique AF to its input, it’s like the data’s personal “fingerprint”. It’s lit! 🤙

This makes hashing a GOAT move to keep your data secure when sliding through the wild west of the internet. Data integrity is just about vibes not being tampered with on the low.

When you get some data, peep its hash vs the OG to see if anyone’s been acting sus. 🔍

If I slide into your DMs with both the msg and its hash, you can hash the msg you got and do a little TikTok to compare. 🕺

Let’s be real with a simple example: We’re grabbing munchies and I remember last time…

Ngl, you’re awesome peeps, but your smell? That ain't it chief. 😬

So I’m like, “Yo, can you hit up the deodorant?”

Before I toss this your way, I SHA-256 it so the hash is like:

33ebb528eab107766343d0ac591952bb68ee959d45b7a8b399628e662f3bc1ef

First, I slap that hash your way.*

Then, here comes the real talk text.

When you catch it, you’re thinking, “Bruh? Did they actually say that, or did this get cooked while flying through the wires?” 🤔

So you let the message ride through the exact same hash function.

33ebb528eab107766343d0ac591952bb68ee959d45b7a8b399628e662f3bc1ef

You throw a side-eye at your hash vs the delivered one.

If both hash values are holding hands, it means:

1. The text slid through like butter, no cap. 🧈
2. Uff, your pits are indeed eesh! 😂
3. Nobody played Minecraft with your message mid-flight.

But remember, IRL it’s all the computers doing this thing for us. 🤖

And hopefully, you keep your vibe fresh. 😅

*For real, I should lock that hash down before it takes off, but let’s keep it 100. How to lock it? That tea's spilt later. 😊

Hashing IRL: Logging In Style 😎

Bet you didn’t know, but you’re in a hashing situation on the reg... like every time you get into your email. 📧

When you set up your email and password, your service isn’t stashing your raw password. Nah fam.

Instead, they whip that password through a hash blender and safekeep the hash. Bless up. 🙌

Whenever you’re trying to login to the email streets, they hash the password YOU throw at them and match-check with their stored hash.

Only if the two hashes vibe together, do you get the thumbs up to slide in. 👌

Let’s talk why they ghost the plain password life…

If they’re holding onto the real passwords, and some digital thieves break in, they could jack those deets. Yikes, not the move if you’re using the same password across the board! 🔓

Hashing to the rescue...

With hashing, deets stay secure even if the baddies get in. They can’t read your secrets, just hashes. 🚫

And chill, hashes are like… vegan burritos, can’t get unwrapped. So, no hackers gonna guess your real password just by peeping the hash, coz it’s scrambled eggs to them.

Every time you log in, your provider just needs the hash to be on their wavelength. 🌊

You type that secret sauce, and it gets blended through the hash magic.

Then they slide it next to their OG saved hash.

If they match up, then you’re good to go. Kick them access doors open. 🚪

If you put in the wrong sauce, the hash won’t vibe, and your attempt hits a wall. Talk about a step back!

So, real tea? Hashing is like encrypting your data in emoji form. Even if hackers sneak into the email shop, they can't translate those encrypted vibes. 😎
