Hash Passwords as they are stored in the database

# ISSUE
One security issue that needs to be addressed in the internship repository web application is the storage of user passwords. To increase security, it is vital that I implement password hashing. By hashing passwords, the application will store an encrypted version of the password instead of the plain text version. This ensures that even if the database is compromised, attackers cannot access the actual passwords.

# FIX
To fix this issue, we can use a reliable password hashing library such as “bcrypt”. Bcrypt allows for the creation of secure password hashes by automatically generating unique salts, which are then combined with the user's password. The hashing process is repeated multiple times to increase the computational complexity, making it harder for attackers to crack the hashes.
