Well, with regex searches, and enough hits to the host, you could use binary searching to figure out the exact text of the scratchpad. Presuming printables (and newline) only, it'd take only 6 or 7 hits per character you wanted to guess. Look for /^[a-m]/ and if that fails, look for /^[n-z]/, otherwise look for /^[a-h]/ and so on. As you get each letter, you add it to the beginning: /^v[a-m]/.

So, yes, this is a leak, but a slow leak.

Hmm. That'd be an interesting article about why not to allow regex searches against text you can't eventually see. >>todo.

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.
