Do not use a normal hash function to store passwords. If the password 
file is stolen, the attackers can quickly determine most passwords.

There are special algorithms to securely store passwords. Common 
recommendations are: PBKDF2, bcrypt, scrypt.

Explanation from

"Many hashes used for storing passwords, such as MD5 and the SHA family, 
are designed for fast computation and efficient implementation in 
hardware. As a result, they are ineffective in preventing password 
cracking, especially with methods like rainbow tables. Using key 
stretching Algorithms, such as PBKDF2, to form password hashes can 
significantly reduce the rate at which passwords can be tested."
