first, my regex is not perfect, there are ways to make it faster (making it greedy and starting only from start is a good start). but anyway it's slow.

regarding what you are going to do: first you want to use a 16bit MD5 and the count of ones and zeros. the worst case is having all 26 ones or zeroes, so you need 5 bits for that information: that mean for 26 bit of data, you'll get 5+16 bit result. that's about 20% compression.

unfortunately, you can't guarantee that for a given MD5 and number of ones, you'll have only 1 possibile 26bit data. you could analize it and findout how many case you can have at worst and i fear it's more then 32 (if it was 32, you had need another 5bit and the total of data would be 26)

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.
