Assessing the Security of Password Storage in Databases
Storing sensitive information like usernames and passwords in databases raises security concerns. The provided code snippet utilizes parameters to prevent SQL injection attacks but fails to address the fundamental issue of password security.
The Importance of Hashing with Salt
To store passwords securely, it's crucial to hash them with salt. Hashing transforms passwords into a one-way encrypted format, making them difficult to decrypt even if accessed by unauthorized individuals. By using a unique salt for each user, the process is further strengthened, protecting against rainbow table attacks that attempt to match hashed passwords with known values.
Steps for Securely Storing Passwords:
Creating Salt and Hashing Passwords:
Dim password = "mypassword" Dim salt = CreateNewSalt(32) Dim hashedPassword = GetSaltedHash(password, salt)
Comparing Login Attempts:
Dim attemptedPassword = "mypassword" Dim storedHashedPassword = "... (from the database)" Dim storedSalt = "... (from the database)" Dim attemptedHashedPassword = GetSaltedHash(attemptedPassword, storedSalt) If attemptedHashedPassword = storedHashedPassword Then ... (User successfully logged in) End If
By following these steps:
