I completely agree, I watched so many videos trying to understand why SHA would even be used, and none of them answered it until I watched yours. And you had fantastic content through the whole video as well, so thank you.

[@holo23]

You earned a sub. I really love the way you explain what hashing is and even gave an example on how to use it for storing passwords. I didn't even notice that it was almost 20 minutes that I was listening to your lecture. 10/10 would recommend this channel to other people again.

wow, thank you so much. "... never see a windows or Mac ..." joke cracked me up 🤣

[@Applest2oApples]

So in other words, whenever a service tells me that my new password is “too similar” to my old password, they aren’t hashing my passwords and basically fucking me over?

[@Ted1A]

They might be encrypting your password

[@weltrepublik]

They're mostly trying to deffend your account from successful brute-force attack

[@Applest2oApples]

@@weltrepublik But if a password is changed by even a single letter and the hashes come out completely different, then they should have no way of knowing that's it is similar. Thus they must be saving my plain text password in order to compare. Doesn't sound like they are defending me at all.

[@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 :)

[@ro-ce8vg]

@@jankastbjerg4017 the fact that a password is similar to a previous one is besides the point, the point is the website knows what your password is, and doesn’t only have it’s hash saved

Main difference is that encryption is 2 way(Can be reverted to original string),
and Hashing is 1 way(Cannot be reverted to original string)

Why can’t it be recessed

The complexity of it makes it nearly impossible to reverse.

[@bigdave3479]

[@OliverEckstein]

Thank you for the great video! I found it really helpful! I have one question regarding the fraud using hash function collisions. How can an attacker "take" the signature of the original document and transfer it to the document prepared for fraud if we talk about a digital signature using private/public keys?
