Q: Which of the following techniques may strengthen and make it harder for hackers to utilize passwords and password hashes?
- Using an uncommon password.
- Running passwords through the hashing function multiple times.
- Using randomly chosen and large password salts.
- Use passwords that are known to be strong.
Explanation: This method, which is also referred to as key stretching or hashing with iterations, increases the amount of computational work that is necessary to break the password hashes, which in turn makes brute-force assaults more time-consuming. Before hashing a password, salts are random values that are added to the password. This ensures that even if two users have the same password, their hashes will be distinct from one another. Precomputed attacks, such as rainbow tables, may be defended against by using a big salt that is unique to each password. This increases the level of system security.The majority of the time, strong passwords are lengthy, complicated, and consist of a variety of characters. Since this is the case, they are more resistant to dictionary attacks and brute-force attacks.
