Webbbcrypt has a significant advantage over a simply salted SHA-256 hash: bcrypt uses a modified key setup algorithm which is timely quite expensive. This is called key strengthening, and makes a password more secure against brute force attacks, since the attacker now needs a lot more time to test each possible key.
