Synopsis

Excerpt from Cryptography I have no intention of writing a complete manual of cryptography. Finality, even very relative, is not attainable in the domain of this art. Besides, good manuals are in existence on this subject, and the titles of some of them will be found at the end of this volume. A cryptographer of considerable experience, however, can always add a few details even to the most complete works of this kind. My object in writing this book is simply to explain what cryptography is, and to recall what it has been from antiquity to the present day; in short, to relate my experiences as a decipherer. The first part of the volume contains a description of the principal systems of cryptography, together with a note on the role played by cryptography in history. In the second part I relate how I succeeded in deciphering a dozen cryptograms of various kinds. In some chapters of this section I give the texts just as they came into my hands; but in the majority of cases, though preserving the system of cryptography actually employed, I have, on grounds of expediency, substituted an approximate reading for the actual text and have modified the plan, and even radical features of the narrative in such a way as to render abortive any attempt at identification and localisation.
