Showing how the birthday problem is a hashing algorithm computation more directly allowed me to finally make the connection I needed. I've almost finished my applied math undergrad and com sci undergrad and no one explained these concepts so clearly! Maybe I just needed to see it presented differently, but this worked wonders for me to link my math to it.

@jankastbjerg4017

@@Applest2oApples it's not that they're neccessarily saving it as plain text, but to make it harder to brute for hackers. fx. most people use the same password on every site, so say a hacker gets your password from another not so secure site, but doesn't exploit it in a way you notice, he now has access to everything you have. now X time later, your pasword gets "expired" on a site, and you change it to something similar, then the next time the hacker tries to login to that site, he will be denied. Now instead of starting to brute force your new password from scratch (A-Z), almost all hackers will start brute forcing through variations of the old password instead, because most people are lazy, so there's a high propability, that only 1 or 2 letters have been capitalised, or changed and etc.... so just changing a few letters will make the hackers use relative short time to brute your "new" password" (from minutes to a few days), where a totally new password will force them to start from scratch, which means the hacker basically have to be incredibly lucky to crack you new password, as long as you use somewhat secure passwords (upper and lower case, numbers and special chars, and a good lenght) the above example is also why it's important to use different passwords for each "important" site you use, and not just variations... hope it made it somewhat clearer :)

the common practical way: 1) encrypt+hash+salter 2) Data send through encrypted package 3) Unencrypt the received data 4) Check on the hash and token should return valid/true. 5) do the things... Regarding MD5, shouldn't really use it, if still insisted, must merge with add-on unique hashing algorithm to generate the only unique result. In reality, there are still tons of systems still using the MD5 hashing basis but they modified with other unique hashing algorithm.

Very good video. That said, I don't think it is accurate to say that increasing the hash length reduces the chance of a collision to "absolutely zero." Certainly the probability of a collision occurring would be incredibly low, but people still get struck by lightning even though the probability of that occurring is vanishingly small.
@SoorajKumarR
2 жыл бұрын
Would it be fair to say that a 100-character hash is way less likely to go through collision when compared to people being struck by lightning, which is a 1 in 60,000 chance scenario? The exponentiality is vastly different, no?

@16:35 I would like to disagree about "salt" Salt is technically speaking a compound that can bind either positively charged ion or negatively charged ion except hydroxide ion (OH-) and hydrogen ion(H+). In some field salt is used as a mode of transport through bonding with adjacent ions. When the condition is right, the bonding will broken down and release the appropriate content. One example is calcium carbonate. When dissolved with hydrochloric acid, calcium is released from carbonate ions. So imagine this analogy to the hashing it is quite similar.
