![]() The difference between encryption and hashing is: Encryption is a way to store passwords but not secure enough. With passwords being the sole means of authentication within apps, applications need some means to store passwords to allow users into their accounts. The Difference Between Encryption And Hashing It’s a hash value of a plaintext a user chose as a password. The value you see in the preceding screenshot is not an encrypted password. This value results from a password-hashing function it’s how some frameworks securely store users’ passwords in the databases. The above is the password hash of a user’s plaintext password in the database. In a Ruby on Rails console, if you’re using say Devise and you query a user with a password, you’ll see something the looks like gibberish. How are passwords securely stored in a database then? Let’s examine the underlining technology that safely keeps user passwords in a framework like Ruby on Rails. Whichever way, you persisted user passwords in some way. You may have implemented authentication in one of your apps, either directly with Rails’s has_secure_password or indirectly through a gem like Devise. ![]()
