I am academically interested in obtaining a program for aiding in the decryption of simple substitution ciphers. Are there any available programs or algorithms in public domain? Thanks, Jason De Mont AT&T mtuxo!jasond

Software to assist in the solution of several of the basic types of ciphers is readily available from members of the American Cryptogram Association. A lot of it is in one or another dialect of BASIC, and most of it has been written for one or another variety of home computer. Some of it is very slick - it's amazing what you can do with an online dictionary, some pattern word lists, and digraph frequency counts. The co-ordinator of the A.C.A.'s computer supplement (I guess he's really its Editor) is an enthusiastic chap who will probably be more than willing to help you find what you need or at least point you at the right person. Besides the semi-annual computer supplement, the bi-monthly >Cryptogram< carries a computer column which discusses using PC's to assist solving. The programming is intentionally pitched at computer novices, but the cryptanalysis represents the distillation of the body of amateur expertise built up by the Krewe over the past thirty years or so. Anyway, the person to write to is: Mike Barlow 5052 Chestnut Ave Pierrefonds, Quebec, CANADA H8Z 2A8 Tell him you got his name from me; that will give him another thing to curse me for!
