Creating secure passwords requires the use of encryption techniques. Encryption is a process that applies a mathematical function to data to produce a unique string output that protects the password. You will learn the basics of creating secure passwords for Ruby on Rails 4 applications. You will also learn how to encrypt a password, store the results and check to see if user login attempts match the information stored in the database.
…To create secure passwords, we will need to encrypt them.…Encryption is the process taking a string of data and applying…a mathematical function on it, to produce a unique string of output.…Knowing the encrypted string, won't give the password away.…And the original password can't be reversed…engineered, even with a lot of computing power.…The encrypted string will be unique so that it can only…be recreated by using the same password with the same inscription algorithm.…In short the only way to have a…password match will be to know the original password.…And that's what we want.…
The most important rule about passwords is to never…ever store passwords in your database as plain text.…Always encrypt them.…If they are in plain text, then anyone who gains access to your database.…Will have every users password, and it's not just hackers…on the outside that you have to be concerned about.…Authorized users are a real concern too.…Any site administrator, employee or someone with database access…has the potential to know all your user passwords.…
