<br>
And one more question, if i am using a salt with the password for computing<br>
a hash value i need to store the salt for future reference and what about<br>
the scenario when attacker gets that salt and hash. That time it may be<br>
reversible right?<br>
<br>
Please tell me the correct method to use a salt with password for storing a<br>
passwords in a secure manner.<br>
