I'd go with solution #3, using an unencrypted comment that indicates the code has been encrypted. Yes, the user might remove or change it, but the user could just as easily fiddle with the encrypted form of the code itself. So, I don't think it's worth worrying especially about the integrity of the comment.

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


  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
  • Posts may use any of the Perl Monks Approved HTML tags:
