Crypto Challenge Contest – Video 2

#cryptology, #cryptography, #cryptanalysis This is the second video of our first "Crypto Challenge Contest". For detailed descriptions of the rules, please watch the video :-) Rules (short version): - You may break ciphertexts and win points. The one with the most points at the end of the contest wins a copy of Gaines’ book “Cryptanalysis: a study of ciphers and their solution”. Another winner will be randomly chosen from all other participants - The contest is in no way connected to or sponsored by YouTube, Google, or Facebook - Everyone (who is no CrypTool team member) is allowed to participate – you don’t need to be a subscriber of our channel or our Facebook page. Participation is for free - At the end of the contest, we will delete all personal data (e.g. names and email addresses) - The official start of the contest is the 14th August 2020 - Solutions may be sent until the release of the next contest video- The basic idea of the contest: having fun with solving crypto challenges :-) Hint: Clearly, everyone is only allowed to participate ONCE in the contest. Thus, if you send solutions for a video multiple times, e.g. from different email addresses, you are removed from the contest. If you are interested in learning the basics of cryptology, you should also have a look at our video series about basics of cryptology – also for beginners: https://youtu.be/jbumW7Ym03o You may download the latest version of CrypTool 2 from here: https://www.cryptool.org/en/ct2/downloads Transcriptions: Ciphertext 11: AVDGAAFAFAADADAAADAADDADDGFAAAFDAFAAADDGFADFVDFADXVFG FFFVAGXFFVVVXAGGGVXDXFFXVXXDGGGVXDFAADFDADFFDAFADAAAF FAFGFFDAFAFDAAADAGFFDAGDAVXGVVFDDFDVDDAXVXXVGDXVFXXXV FDVDGGDXVFXXDAAFAAAFFDADAGAGAFGFAAAVADAGDDADADDDFAAD AGDXVDXGGXDXVXXGXGDXDDVVDGFVXDGVAXXGVXFFFVXDG Ciphertext 12: SIKUQFVIDFSBKOKCTMUMQFVIDFSTRQBQDPWBKCDQTUPOKUQFVIDFSB KOKCTGQCLBPSFQTXNWPBUSHDCPBSZOYOPOUDHNOHRQABOCVBTUK CGKSTQOOYBUFQIOMWBLTQCRYOUQYOPODHNKBUYSKCXHKCPBVBTHL XCPUDECXDFCQMCUXGABUTYTPCCLCOBLAEFLUDUMQFVIDFSW Like what I do 😄?
