Password storage

- [Instructor] Unlike encryption, for passwords, … we want to store passwords in such a manner … that we can't and no one else can tell … what the original password is. … The reason is is because we only need to ensure … the password a user enters matches what we have stored. … We should never have a need to transmit a password, … and we should never need to know … what the original password string is. … We do this via what's called a hashing algorithm. … Hashing is where we convert a string … to another completely different string. … The property of a hash that we're taking advantage of … is that a hashing algorithm is a one-way operation. … A hash can't be converted back to the original string. … And the same original string … will always create the same hash. … The library has a variety of courses … that cover both hashing algorithms in detail … and password storage in more specific detail … than we'll cover here. … We're just going to explore it … as we can deal with it in Larevel. …
