Description
Returns a salt to add to hashes.Salts are created using secret keys. Secret keys are located in two places:
in the database and in the wp-config.php file. The secret key in the database
is randomly generated and will be appended to the secret keys in wp-config.php.
The secret keys in wp-config.php should be updated to strong, random keys to maximize
security. Below is an example of how the secret key constants are defined.
Do not paste this example directly into wp-config.php. Instead, have a
{@link secret key created} just
for you.

Salting passwords helps against tools which has stored hashed values of
common dictionary strings. The added values makes it harder to crack.
