Hy!
iam going to decide to SHA_512 with salt in my web project.
ut iam still in confiusion that there is some problem in it..
the hashing algorithm just hash the data before saving it in to the database something like ( 45454dsdsd54d4sd ).
how can the admin know about the user password?
how can he access to his personal data/profile?

if there is anothr way to secure the user input data in web please tell me...
Thank's.
