In this movie, we're going to learn about another important concept in encryption …and in password security, which is the concept of salt. …Before we talk about salt, we first need to talk about rainbow tables, because …that's the main reason that we need salt. Now imagine that a hacker gets a hold of …our database. But we've been smart and we encrypted our database. …Let's say we encrypted it using the SHA-1 algorithm. …So, those are now all encrypted and you can not tell what the plain text password was. …but the hacker could take one of those values and then have a little program …that just runs and tries every single value possible.…
Every word in the dictionary, every combination of letters and numbers, tries …everything possible. Looking for a result of the SHA1 hashing …algorithm that matches your result. And if he can generate a result that …matches, then he will know what the input was. …He'll know what the original password was. …So, you may be thinking, well that's going to take a long time, right? …
