A developer has created a password storage scheme based on the following diagram: What is effect of the hash loop which repeated hashes data many thousands of times? How would this improve security of the password file? What is effect of the hash loop which repeated hashes data many thousands of times? How would this improve security of the password file? The hash loop means the chances of guessing the password are reduced because an attacker doesn't know how many times the loop was run. The attacker needs to guess the password AND the iteration count. The hash includes the salt, which means rainbow attacks are impossible. The hash loop extends the password length, making the password much harder to guess. Extending the password length protects against dictionary attacks. The hash loop takes time to execute. By increasing the time-cost of calculating hashes, the password file becomes harder to brute force because each password or brute-force guess takes thousands of times longer to test. The hash loop improves the collision resistance of the hash function. Because all hash functions have a slim probability of a hash collision, repeated hashing reduces the likelihood. Improving collision resistance improves password security
