Java Salt Value Create getSaltedString(String in)

Description

This method takes a string, adds a random salt to it, and returns it.

The random number generator for this method is low security, and should not be used for cryptographic purposes where unpredictability is paramount.

Generally, salts need not be unpredictable, as long as they are not often repeated.
