DarqFlare Posted January 28, 2005 Posted January 28, 2005 Ok folks! Here's a code I want you to break. PM me the exact results of breaking this code. The first person to break it correctly... wins something... I don't know what yet. I'll give you one hint. It is a sentance in English. 42-6E-6C-75-76-63-71-68-70-22-68-78-21-6B-71-77-62-70-6C-76-66-22-6C-79-64-77-71-68-76-6F-23-69-74-76-2F It will appear in my signature as well. Quote
TCH-Dick Posted January 28, 2005 Posted January 28, 2005 You and Rob kill me, I never can get these. Quote
TCH-RobertM Posted January 28, 2005 Posted January 28, 2005 supercalafragilisticexpialadocious thats my guess LOL Quote
Deverill Posted January 28, 2005 Posted January 28, 2005 Here's my guess: Sentence: "Let there be darq" Method: I looked down in your signature (which you said contained the secret phrase) and thought... hmmm.... Quote
DarqFlare Posted January 28, 2005 Author Posted January 28, 2005 Nope, wrong guesses! I probably should have made it "Let There Be Darq" heh... Quote
borfast Posted January 29, 2005 Posted January 29, 2005 Argh! Another cipher! Now I hate both you and Rob, 'cause I can't resist these things and I spend way more time than I should trying to break them! I never got Rob's, though... Quote
DarqFlare Posted January 30, 2005 Author Posted January 30, 2005 Just something to pass the time... Quote
borfast Posted January 30, 2005 Posted January 30, 2005 Robert, can you give us some clues? Like... are those hexadecimal values? I suppose they are, because there's no letter above F... Quote
TCH-Andy Posted January 30, 2005 Posted January 30, 2005 Using a modified hexadecimal system I could get some words - but not the whole sentence, so I'm not sure I was on the right track - I'll have a play again later Quote
borfast Posted January 30, 2005 Posted January 30, 2005 Here's something for you to play with (assuming the hex codes is the right way to go): an HTML/PHP page that writes out the printable ASCII characters (codes 32 through 126), the original string, the same string with all the values converted to their decimal equivalents and then all the possible strings by using Caesar's cipher - it's an encryption method used by the Roman Emperor, Caesar, to send messages to his generals. The encryption algorithm is very simple, consisting of assigning a decimal value to each letter of the alphabet (in our case, the ASCII character set) and then shifting that value by some value. Feel free to improve it ><html> <body> <strong>Printable ASCII characters and their respective integer values</strong> <table style="border: 1px solid black;"> <tr> <?php for($i = 32; $i < 62; $i++) echo " <td style='background: yellow;'>$i</td>"; echo " </tr><tr>"; for($i = 32; $i < 62; $i++) echo " <td>".chr($i)."</td>"; echo " </tr><tr>"; for($i = 63; $i < 93; $i++) echo " <td style='background: yellow;'>$i</td>"; echo " </tr><tr>"; for($i = 63; $i < 93; $i++) echo " <td>".chr($i)."</td>"; echo " </tr><tr>"; for($i = 94; $i < 124; $i++) echo " <td style='background: yellow;'>$i</td>"; echo " </tr><tr>"; for($i = 94; $i < 124; $i++) echo " <td>".chr($i)."</td>"; echo " </tr><tr>"; for($i = 125; $i < 127; $i++) echo " <td style='background: yellow;'>$i</td>"; echo " </tr><tr>"; for($i = 125; $i < 127; $i++) echo " <td>".chr($i)."</td>"; echo " </tr><tr>"; ?> </tr> </table> <br /><br /> <?php $string = "42-6E-6C-75-76-63-71-68-70-22-68-78-21-6B-71-77-62-70-6C-76-66-22-6C-79-64-77-71-68-76-6F-23-69-74-76-2F"; echo "<strong>Original (hexadecimal?) string:</strong><br />".$string."<br /><br />"; // Convert from hexadecimal to decimal echo "<strong>Original string converted to decimal values:</strong><br />"; $string = explode("-", $string); $dec_string = array(); foreach($string as $value) array_push($dec_string, hexdec($value)); foreach($dec_string as $value) echo $value."-"; echo "<br /><br />"; // Convert to text echo "<strong>Strings by 'shifting' each character code by <delta>:</strong><br />"; echo "<table><tr><td>Char code</td>"; foreach($dec_string as $value) echo "<td style='background: orange;'>".$value."</td>"; echo "</tr>"; for($i = 0; $i <= 94; $i++) { echo "<tr><td>Delta = ".$i.":</td>"; foreach($dec_string as $value) { $value -= $i; while($value < 32) $value = 126 - (31 - $value); $color = ($i%2 == 0)?

DarqFlare Posted January 31, 2005 Author Posted January 31, 2005 Hmm, thinking about hexadecimals? Interesting... Hey Andy, just curious, what'd you come up with? Quote
TCH-Andy Posted January 31, 2005 Posted January 31, 2005 Hey Andy, just curious, what'd you come up with? <{POST_SNAPBACK}> well things like 70-6C-76-66 is the word "misc" if you offset the hex by 3. you can get other words by doing more complex shifts - but none would give me a sentence Quote
Deverill Posted February 1, 2005 Posted February 1, 2005 Yeah and the HAL computer in 2001 is IBM if you offset it by one. Quote
borfast Posted February 1, 2005 Posted February 1, 2005 I even got some Portuguese words out of it but still no complete sentence... Quote
DarqFlare Posted February 2, 2005 Author Posted February 2, 2005 Alright, time for a hint. Andy is on the right track by trying to offset... It's a step in the right direction at least. Quote
