title: Storing hashed information as VARBINARY on SQL
body: <p>I'm using the PHP <code>PASSWORD_HASH();</code> and <code>MCRYPT_ENCRYPT();</code> *MCRYPT_RIJNDAEL_256* for password/string encryption.</p>
  
  <p>Is it safe to store them as VARBINARY on SQL and what need to be the maximum length of the column? Also, what is the maximum?</p>
