A hash is designed to act as ”one-way-function” making it easy to perform but very hard to reverse. The reason why this is so beneficial when it comes to password managing and login handling, is because it allows the developers to convert the original password into a unique phrase that can be stored in the database. By using a hash function the application don’t have to match the original password in clear text with the password given upon login as it does not know what that password is. Instead it only need to know what hashing function where used and then see if the password entered generates the same hash value as the one saved in the database. This little trick provides the same login functionality as when all passwords were in clear text but the difference here is that now it’s only the user who knows exactly what the password is. Is Hashing flawless? However this technique is not flawless, as nothing is really secure when it comes to Information Security. Since the has...
