How To: Use salty hashes to keep passwords secure

In this tutorial, we learn how to use salty hashes to keep passwords secure. A hash is stored in a database that is hashed with an algorithm, so not everyone can see exactly what your password is. When you type your password into a website, it doesn't actually register as words, it registers as a hash. This keeps your passwords secure so not everyone can see them. Salting is when you use random pits and attaching them to your regular hashes so not every password is the same. The salt is what ...
