Transcription of the report reads: truqnujkbtvfqajaoaj n qgqwlbdrtmdeavabasnnq ljxcwfislmam m tn h


The book, which I have never found a few hours marathon ciphertext, which did not have a solution, the noble German called Die Geheimschrift der Carbonari: zum allgemeinen praktischen Gebrauche in allen Sprachen Für Telegramme, Korrespondenzkarten, g66 INSERT und sonstige Vertrauliche Mittheilungen. Leicht fasslich dargestellt, sowie mit und Tabellen Beispielen versehen, and was printed in Vienna, Budapest and Munich in the said year 1875. Its author was none other than Mr hiding under the pseudonym Arthur Storch (l. Named Julius Franz Schneeberger), incidentally techniques and writer, telegraph office worker and hypothetically conclude that even famous Austro-Hungarian Cabinet Schwarze Wiener Polizei ... :) Of all the rings and rings and secret societies, but Carboneria among those less known. Therefore digress a little. Carbonari were Italian secret society pretends to Italy nationalism and liberal ideas with protipápežským and protimonarchickým focus. After a series of uprisings in protipápežských r. 1831 b ola later suppressed by police methods. Freemasons but I think we all know, therefore I shall describe itself. The front page of that book is as follows:
Transcription of the report reads: truqnujkbtvfqajaoaj n qgqwlbdrtmdeavabasnnq ljxcwfislmam m tn h ncwmamqwaxtup g at the literature g66 on cryptology is a security methods reports, which used the Carbonari obvious reasons wrote relatively little. World-known cryptographic historian David Kahn them in his book The Codebreakers page. 773 and 787 mentions total 2. Neither g66 of them, however, g66 not attest to our message. (Selection process does not describe ...) The author of the encryption process by which allegedly used the Carbonari in several examples of how it was used ... So p. 6 in his book states that: "Let's say we encrypt a message stating: Theodor Huber fallirt dieser Tage gewiss salvirt euch, with a key Roma. ..." Etc. Follow the steps in the book, you'll see that the method closely resembles the already very familiar Vigenère cipher type.

After several attempts, I found that it is a variant, which is known in the literature as a method of Admiral Francis Beaufort. If you encrypted messages as St - ciphertext, password as H and decrypted message as OT - plaintext, so we can write t = H - OT, with addition and subtraction are done so. Modular, without transfer. OT = H - TH Let's say we have the letter T encrypt passwords using letters, ie. R. The letter T in this case is 19, and R is then 17. The first point is related encrypted management RT = 17-19 = -2 MOD 26 = 24 i.e. A. For the second point, we get: OH = 14-7 = 7 mod 26 = 7, ie. H, and the like. What is the numerical value assign a letter, can also be seen from the following table: ABCDEFGHIJKLMNOPQRSTU VWXYZ 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 Likewise also recommended when decrypting messages only from Letter password readings modulo letters of ciphertext. Deciphering encrypted messages Beaufort g66 method is no longer a little complicated, so do not go into details. But for those interested, I refer to Kasiski test and Friedman's index of coincidence ... :) I came finally to wishful meteo, but there was a "minor" problem. After shelling, I suddenly froze ... and found that the content of the encrypted message is essentially racist considerably, so I had a dilemma whether it be noted on his blog or not. But for historical reasons, I finally opted for the former. ... Password: NEGERAUSDARFUR g66 NEGERAUSDARFUR ------
