I have a short string (8-12 characters) that I need encrypted, but I want the encrypted string to be as short as possible. It does not need to be secure, just needs to essentially hide the original string from the user. I've tried several different encryption algorithms like Crypt::Blowfish and Crypt::Simple, but they all create a huge and long encrypted string (like this: zL3BCn5IdDCkG8eCDhESvadH92FNoMbbCTB2Fu4Cq4ynsNHL+m+h8lbCa1NshUMf==).
