Eve has just discovered and decrypted the file that associates each userid with its 32-bit random salt value, and she has also discovered and decrypted the password file, which contains the salted-and-hashed passwords for the 100 people in her building. If she has a dictionary of 500,000 words and she is confident all 100 people have passwords from this dictionary, what is the size of her search

space for performing a dictionary attack on their passwords?

What will be an ideal response?

The size of the search space is 100×500,000, which is 50 million. This is due to
the fact that the attacker needs to do the dictionary attack against each person separately,
because of the password salt.
