What are some common mistakes when using bcrypt for password hashing?

Some common mistakes include using a low cost factor, not salting passwords, and failing to handle errors properly.

Why is the cost factor important?

The cost factor determines how computationally intensive the hashing process is, affecting security and performance.

Can you explain what salting is?

Salting adds a unique random value to each password before hashing, preventing identical passwords from having the same hash.

What happens if I forget to salt the passwords?

Without salting, identical passwords will produce the same hash, making it easier for attackers to use precomputed hash tables.

How can I properly implement bcrypt in my application?

You should use a library that supports bcrypt, set an appropriate cost factor, and always salt passwords before hashing.
