Showing the Oldest Printed Book on Cryptography: Trithemius‘ „Polygraphiae“ and www.cryptobooks.org

#cryptology, #cryptography, #cryptanalysis In this other kind of video, I present another project that I am currently working on – besides CrypTool 2 :-) www.cryptobooks.org is an online bibliography of literature about cryptography. Together with Tobias Schrödel I maintain this online bibliography. Our goal is to collect information (and pictures!) about historic books about cryptography. In this video, I present our cryptobooks webpage and also show the oldest (and first) printed book about cryptography: Trithemius' "Polygraphiae libri sex". Also, Tobias and I are always searching for information on books, pictures, etc. So if you have these, contact us, thus, we can upload these to the database. A last word: cryptobooks.org is a free and open database for everyone interested in the fascinating topic of (historic) cryptology. I also use this video as a first test of my greenscreen and my new camera. So please be gentle. I know the recording quality and lightning is not the best (yet), but it is a first start... maybe in future videos, I will also use the green screen and camera to show my face :-) One note: I mispronounce the last shown book of Gaspar Schott in this video (as I always do with this book title :-) ). It is not "Schola Steganographia" but "Schola SteganographiCa" (with a "C"). One final note: Trithemius presented in "Polygraphiae" his "tabula recta" (which comprises of shifted alphabets), which I do not show in this video. In fact, this is used for his so-called "Trithemius cipher", which is a polyalphabetic substitution cipher (comparable to the Vigenère cipher, but without a key). In one of the next videos on the channel I will discuss this Trithemius cipher in detail ;-) Link to cryptobooks: https://www.cryptobooks.org Link to "Polygraphiae": https://cryptobooks.org/book/92 Some other stuff on the channel you might be interested in: If you are interested in learning more about cryptology, I suggst you have a look "Basics of Cryptology" series.
