Way of Hashing
Hashing is a way of securing our data. Hashing is
not used for reusable data, since the feature of backing up original data is
not present in the mechanism of Hashing. At current, Hashing has become a way
to restore passwords into the database. This is done by the user registering
into a system using password and the password will be converted to an other value
and will be stored in the database. However, Hashing is not advised for storing
data, since Hashing works be randomizing and not ordering data. Hash value is
one of the main features for not retrieval data. For example when a password is
used on a system, it will be stored under Hash value. When a password is given
in a system under the Hash value the system is likely to save the password and
make the login time quick. For this to happen the old Hash value and new Hash
value has to be matched, if they are not matched the log in will be failed and
only if Hash value matches the log in will be successful.
- · Hash collision
Sometime two different input gets same hash value it’s called
as hash collision.
- · Salted Hash
Sometimes two users have same password use on same system. if
one user is an attacker and if he is going to attack the system. he can get the
real value of the other user password. So this situation is threat for other
user. System gets password from user also add some random value with password
after that hash the password and store. It’s called as salted hash Now attacker
can not find any users password.
