Salted Passwords are good. but, if old algorithms like MD5 then it is no use

In case of Mathway, the storage mechanism for the passwords is PHPASS, which gets salted MD5. Allan says " if I wanted to crack these passwords,I could do so on a rig that computes millions of MD5 hashes a second. With more secure cryptographic hashes, such as bcrypt or scrypt, it is much slower to compute the hash."
