Could someone please confirm the following for me:
Is the point of encrypting passwords when saving them into a database that if the database is hacked into then the hacker won't be able to know the actual passwords, unless s/he has the algorithm and salt etc to decrypt it, and therefore won't be able to compromise this or other accounts using the same password?
But my main query is: presumably the password is encrypted in, for example, the PHP script that saves the password into the database, and therefore the algorithm to decrypt the password is clear in that script. So is it correct that if the hacker hacked into the server or content management system for the website s/he would be able to access that script and decrypt the passwords?
So essentially the encryption is only as relevant as your login information to your online CMS or server is strong?
Thanks in advance!
