In Angular applications, password storage and encryption are typically handled using a combination of server-side and client-side techniques.
On the client side, Angular provides built-in form validation to ensure strong passwords. Additionally, you can use HTTPS to encrypt data transmission between the client and server.
Server-side is where actual password storage and encryption occur. When storing passwords, it’s crucial to hash them using a secure hashing algorithm like bcrypt or Argon2 before saving them in the database. This ensures that even if an attacker gains access to the stored data, they cannot easily reverse-engineer the original password.
For added security, you can implement salting by generating a unique random value for each user and combining it with their password before hashing. This prevents attackers from using precomputed tables (rainbow tables) to crack hashes.
To verify a user’s credentials during authentication, hash the provided password with the stored salt and compare it to the stored hashed password. If they match, grant access; otherwise, deny it.
