( #3333=superdoc: print w/replies, xml ) Need Help??

kschwab, I have seen what you posted here: Encrypting Source Filter. Thanks!

It makes very clear what one has to do to achieve what I wanted, re: encryption and file contents eval. Also, by asking for a password to decrypt, it avoids saving the password in the file (like Module::Crypt does) which would be plain trivial to extract even without brute-forcing!

Based on your example, I will try to roll my own solution which will address one more concern I have: including (own) modules. All by specifying a single password. And also add a feature to load from net as well as from local file. I wanted to make the spec clearer in my mind before leaving an answer to your post.

On the other hand, I do not want to make too much noise out of this, maybe even placing this post was too much AFAIC, because I see code encryption like administrating hemlock for treating a very special case but can soon spread into mass hysteria.

The only weakness to this method is that one can attach to the script process and make a memory dump. With all modules loaded in memory, it would be easy to figure out the encrypted code and its structure. But if a hosting company takes such an effort to peek on my code then I would lick my wounds and put it on my CV!

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • 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).
  • Want more info? How to link or How to display code and escape characters are good places to start.
