AZdecrypt 1.19 by jarlve@yahoo.com (10/11/2020) dd/mm/yy -------------------------------------------------------- A powerful multi-threaded letter n-gram based substitution cipher solver for Windows since 2014. Originally written in attempt to solve the Zodiac Killer's unsolved 340 code. FreeBASIC: http://www.freebasic.net/ Simple GUI: http://www.freebasic.net/forum/viewtopic.php?f=8&t=24617 Discussion and support: http://www.zodiackillersite.com/viewtopic.php?f=81&t=3198 - FreeBASIC version 1.07.1 using GCC 5.2.0 / GCC 8.1.0. - Reddit n-grams version 1912. - beijinghouse n-grams version 6. - Thanks to beijinghouse @ www.zodiackillersite.com for: -------------------------------------------------------- --> Providing excellent all-around n-grams that were compiled from a multi-terabyte corpus. --> Special no-compromise low memory n-gram format. --> Recoding the n-gram loading routine so that it is up to 20 times faster with the added support for loading n-grams directly from .gz files. --> Several code optimizations to the solvers which increase speed by up to 10%. --> N-gram score calculation abort routine which speeds up the solver when using higher n-gram sizes. --> The many suggestions and working with me on AZdecrypt from 2019 to 2020. --> Monoalphabetic groups solver idea. - Thanks to Geoff L. (smokie treats @ www.zodiackillersite.com) for: -------------------------------------------------------------------- --> Helping me design and test the "nulls and skips" solver and for the creation of countless test ciphers and cipher statistics. --> the idea for the "row bound" and "row bound fragments" solvers. --> the 2-symbol cycles idea. - Thanks to David Oranchak for all his work surrounding the Zodiac ciphers and cryptology. And for spreading awareness about AZdecrypt. - Thanks to Richard @ https://www.freebasic.net/forum/ for his fast exponentiate approximation function. - Many thanks to the people of the Zodiackillersite cipher forums for their help and support: daikon, doranchak, glurk, Largo, Marclean, Mr lowe, smokie treats, f.reichmann, beldenge and many more. - Many thanks to the people of the FreeBASIC forum for helping me out with code issues: counting_pine, dodicat, fxm, jj2007, Lothar Schirm, MichaelW, MrSwiss, paul doe, PaulSquires and many more.
