HS-HASH 1.1.1

HS-HASH is a data hashing class that uses a secure hash algorithm and returns the hashed value of the entered string. For security reasons, you may want to store passwords in hashed form. This guards against the possibility that someone who gains unauthorized access to the database can retrieve the passwords of every user in the system. Hashing performs a one-way transformation on a password, turning the password into another String, called the hashed password. “One-way” means that it is practically impossible to go the other way - to turn the hashed password back into the original password. HS-HASH also includes several options for encryption/decryption and more.
