#### The History and Mathematics of Codes and Code Breaking

While perusing Elonka’s website, I was fascinated by her page of “Famous Unsolved Codes and Ciphers”. Like Sara stated in her blog post, it is so astonishing to think about how even with modern technology and current knowledge, there are still numerous ancient ciphers that have yet to be broken, including the Beale Ciphers and the Voynich Manuscript.

I was not surprised that the Beale Ciphers was seated at the top of the list, which was ordered in terms of “fame.” In class, we discussed how its popularity most likely stemmed from the monetary prize associated with cracking it. Both professional cryptanalysts and amateurs have taken a crack at the Beale Ciphers, motivated largely by the potential of finding \$20 million worth of treasure.

Although we have discussed the Beale Ciphers at length in class, the majority of the ciphers on the list were foreign to me. I found the Voynich Manuscript to be particularly intriguing. The Voynich Manuscript, which was constructed in the early 1400s, is a staggering 232 pages long. Its uniqueness stems from the fact that it not only contains text, but that it consists of drawings as well. Eccentric drawings of plants, herbal recipes, astrological diagrams, and humans in plumbing-like contraptions dominate its pages. This makes me wonder: what role do the drawings serve? Do the drawings contain the key to decrypting the text?

In class, we talked about the advantage of having a substantial amount of encrypted text when attempting to break a cipher. The Voynich Manuscript poses no problem in this respect. However, it is written in an unknown script of which there is no known other example of in the world. The script is alphabetic in nature, but shares no letters with any English or European alphabets. While this greatly elevates the difficulty of decrypting the script, it makes the manuscript equally more intriguing as well.

The Voynich Manuscript is considered ‘The Most Mysterious Manuscript in the World.’ Although it is possible that it is just a great hoax with no true meaning, crpytanalysts continue to devote extreme amounts of time and effort towards decoding it. Not only would decryption explain the strange drawings, but it would also reveal a new language never seen before. The Voynich Manuscript is simply fascinating; how and when it will be solved still remain a complete mystery, but I eagerly await its decryption.

The Voynich Manuscript is a trip. I suspect it's a hoax, but I hope it's not. I'd love to know more about the person who put together such a strange combination of science and fantasy.
