What Are the Disadvantages of Hashing Passwords?

Discover the risks associated with hashing passwords and how to secure your applications effectively.

64 views

Hashing passwords have some disadvantages such as being vulnerable to brute-force attacks if proper hashing algorithms like SHA-256 or bcrypt are not used. Additionally, rainbow table attacks can crack hashed passwords if they are not salted. To mitigate these risks, always use strong, modern hashing algorithms and incorporate unique salts for each password.

FAQs & Answers

  1. What measures can I take to secure hashed passwords? Always use strong hashing algorithms like bcrypt and include unique salts for each password to enhance security.
  2. What is a rainbow table attack? A rainbow table attack uses precomputed tables of hash values to quickly crack hashed passwords if they are not properly secured.
  3. Why is salting important in password hashing? Salting adds unique random data to passwords before hashing, helping to prevent attacks like rainbow tables.
  4. What hashing algorithms should I use for password storage? Modern algorithms like bcrypt, Argon2, or PBKDF2 are recommended for strong password security.
