Title: I have a little puzzle for you folks! Post by: armedmilitia on January 13, 2016, 04:10:09 PM I also posted this on reddit: https://www.reddit.com/r/Bitcoin/comments/40slwf/i_have_a_little_puzzle_for_you_folks/
Pubkey: 1LDaBuUgUgNGDuensc96vXAtvvb8iijhoJ It should contain 0.04 BTC. If you get the private key feel free to keep it all or leave it for the next person. Your call. Riddle: Code: Check out my pad, bro! I didn't buy it, I wrote it! Good luck! Title: Re: I have a little puzzle for you folks!

Edit: Can't find a g :-\ Title: Re: I have a little puzzle for you folks!

Well, finders keepers. The imgur link is a Caeser shifted (hence Clooney in the film Hail Caesar!), which points to this QR code: https://i.imgur.com/7sd5rSW.png The QR code scans to Code: x³˜ÅÓd¹šÊŠÏÀ—»Ã°tRÈź—h¬X¯Ñ›Þ‰ªsÒÚêgšÎ`Rž–¿Ûâ¿Îh¹¬u This is impossible to break if the cipher key is randomly generated and kept a secret, but I provided you the key: Code: Check out my pad, bro! I didn't buy it, I wrote it! You can quickly grab the ascii values of all these characters by looking here: http://asciivalue.com/index.php Then all you have to do is subtract the ascii values from each other. I'll do the first three characters here in detail: Code: Cipher ASCII Value Key ASCII Value Value of (Cipher-Key) Plaintext (Decrypted) The full process: Code: CIPHERTEXT: x³˜ÅÓd¹šÊŠÏÀ—»Ã°tRÈź—h¬X¯Ñ›Þ‰ªsÒÚêgšÎ`Rž–¿Ûâ¿Îh¹¬u And that's how you do it! I wrote a tool in c++ that does OTP encryption, and it will spit out a ciphertext, decrypt, generate pads, take custom pads, etc: It took a lot less time to set up the challenge than to write this post. :) Title: Re: I have a little puzzle for you folks!
