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==).

I would also prefer it to be rather simple to implement.

Any ideas? Thanks!

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
