Israel Torres //--------------------------------------------------------------------------// 100$USD Crypto Challenge of the Month.... (July 2008) ... and we are back to the 100$USD Crypto Challenge of the Month for July 2008 ... All you need to know resides here: 208 243 241 230 223 215 205 219 198 227 219 251 259 219 212 229 208 224 207 214 209 233 229 231 257 235 210 226 201 219 209 211 236 241 230 240 221 The first person to submit the solve to this crypto correctly by Friday July 11th 2008 5PM (my time) (just in time for the IVU meet) by email reply ONLY will be handed 100$USD free and clear (at the IVU meet). Aside from the solution you must include visible detailed steps on how you solved this. Challenge Hint A: This crypto system has been artificially weakened so that it is solvable during these time constraints since it is Wednesday July 9th (day of posting). Challenge Hint B: The weakening mentioned in Hint A may have made it _way too weak_ and I didn't have time to test just how weak - let me know ;) You must be present to collect the prize and no substitutions - there will be only 1 official winner - offer expires at 5PM 07/11/08. Additional notices: - Unfortunately I myself may not be present during the IVU meet on the 11th due to my travels but will make sure that the official winner claims their prize without hassle (if there is one). - I will be at Blackhat USA 2008 Las Vegas and Defcon 16; otherwise will be on travel mostly until then. Thank you and good luck. Israel Torres //--------------------------------------------------------------------------// 100$USD Crypto Challenge of the Month.... (September 2008) re: (August 2008) Doesn't it seem like we are always running out of time? Well it sure does to me. For those that missed Defcon 16 you missed the August 2008 Crypto Challenge of the Month. I bet you thought I forgot... but I didn't. In fact for those that noticed at Defcon the challenge was printed on the shirt no less being sold at the IVU booth and is as follows: 85 851 12 808 58 686 71 866 98 275 87 855 38 481 861 08 718 14 91 129 78 570 66 708 21 081 00 838 41 087 87 88 54 85 790 83 855 78 686 48 868 88 185 11 269 81 107 11 288 85 487 46 986 69 826 78 586 10 081 82 107 74 978 64 973 61 ^^^ I c/p that above so that you don't have to get eye strain in case you have the shirt. There are also a few other details about the shirt that should have given you a few hints. Have fun if you still haven't figured it out :) But no one ever contacted me with the solve (sad face). Some of the Defcon crypto t-shirts may be avaiable at IVU, just ask Freaky ahead of time. Anyway that was August's crypto challenge (now expired) and let's move on to this month's September 2008. ---- snip ---- 100$USD Crypto Challenge of the Month....

Aside from the solution you must include visible detailed steps on how you solved this. Challenge Hint: "Sometimes you have just just stand back and take a look at yourself." Misc Info about this particular crypto: I wrote it in about half an hour at the car dealer watching "Live Free or Die Hard" while listening to Flyleaf. It is written programmatically so I can encrypt arbitrary strings. Which I am sure you love. You must be present to collect the prize and no substitutions - there will be only 1 official winner - offer expires at 5PM 09/12/08. For those interested I may be doing a crypto pop quiz at the meet so bring your brains. I have one Defcon 16 Challenge coin ( pictured http://tinyurl.com/5sra3o ) and a crypto book for the first to win the pop quiz. Thank you and good luck.
