Cool! I liked what you made, and you are right, documents like word, pdf, have the same header, and using this information we can use brute force to get the headers, and geting the headers we can get the rest. But if we use another block size (not 1024, the default) and a key with 20+ digits will be very difficult. To make a better cipher we can just add something to mask the headers too, or encrypt again the data!

The James Bond cipher are not based in the source of the ABC1, just in the idea to move bits.

But remember, I made this for fun, this is the only cipher that I made! I never used this for real, because I don't have top secret things! Every thing that I made is for Open Source. Why I will encrypt what I will publish for the world!?

And "no_slogan", DMCA can't kill our liberty of expression. Nice code! And Cryptography is legal, because without it internet can't exist.

• 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).
