"Elonka". In 2006, Dunin compiled a book of several hundred exercises in classical cryptography, which was published in the United States as The Mammoth Book of Secret Codes and Cryptograms, and in the UK as The Mammoth Book of Secret Code Puzzles. The book also includes a few details about several unsolved codes, such as Kryptos. In 2013, in response to a Freedom of Information Act request by Dunin, the NSA released documents which show the NSA became involved in attempts to solve the Kryptos puzzle in 1992, following a challenge by Bill Studeman, Deputy Director of the CIA. The documents show that by June 1993, a small group of NSA cryptanalysts had succeeded in solving the first three parts of the sculpture. Public speaking Dunin has given talks on Kryptos and the Cyrillic Projector'' at the National Security Agency's Cryptologic History Symposium, Def Con, Shmoocon, Notacon, PhreakNIC, and Dragon*Con, and has also given lectures at the International Game Developers Conference. She has been invited to be a co-host on the Binary Revolution webcast three times. In October 2012, she was the guest of honor at Archon. In 2021, she gave a TEDx talk on cryptography, "2000 years of ordinary secrets". Personal life Dunin is a Wikipedia editor who has made tens of thousands of edits.
