Say I have a form field where I input any text(numbers,text,symbols, or mixed). I want to encrypt that input into 16 characters long encryption string that includes at least one uppercase letter, one lowercase letter, one number and one special character? How can that be done? Also I want to decrypt it back to original input as well. Can that be one?
