I have been watching the series so far and I learned a lot since. Thank you for doing such well done tutorial and putting it on the web for free. Technology is powerful and its effectiveness is enhanced by people like you sir.

De-hashing is imposible mathematicly that is why it is safe.
Hashing uses functions that can't be inverted so when u use the first parameter that is the actual pass and the second parameter that is the same pass just hashted it grabs the first parameter hashes it and compares it to the second parameter and if that is true it returns "1", that is how i think password_verify() works, since hashing is not an invertable function.
BTW still the greatest PHP tutorials on youtube.

Hello, your channel is fantastic. Did you know how many php classes you have?

[goddessgermanika]

Hi Dani, thank you very much for all those tutorials! In regards to passwords, what is your opinion about salting passwords? I was told that certain companies add it to hashed passwords. Do you think it would be good idea? and if so... do you have a tutorial for it by any chance?

[olegpristashkin]

How can we apply hash when the quantum computer will be finished? So can we assume, that the password hashing will be only a temporary method of protection? Am I right if I say that a good method of protection, in this case, is to limit attempts to log in up to 3 times an hour to avoid brut force?

[CredixNetwork]

Hello Daniel! Can I ask you a quick question? What color syntax/theme you're using? Thanks for the answer and for the great tutorial!

[PHPRunnerTipsAndTricks]

So what is password_verify really doing? Could you test password_hash(input) with passwordinDb with an if statement?

[robinsonenrique]

Is better use BCRYPT or password_Default ?

[mmelimahlobo]

Hie Daniel your teaching is amazing have you considered creating on lengthy tutorial that we can purchase in Udemy?
