Codes have been used since Antiquity. Some hid messages in form of tattoos painted on the heads of slaves. Others mixed letters and numbers to make sure their message would never be discovered. Nowadays we use encryption to protect our passwords and personal details. Many codes have been cracked through the ages. Yet, some remain unsolved even today.
Discover below three codes that have never been cracked:
The Zodiac Killer’s Codes
During the 1960’s and 1970’s a serial killer terrorized the San Francisco Bay area. In order to cultivate fear in the hears of the population, he also sent letters and encrypted messages to the media and the police. At least four of these messages were cryptograms. Until today, out of the four codes, only one was solved. It was a three-part message sent to three different newspapers. The code was cracked by Donald and Bettye Harden; it contained many spelling mistakes. This could be why the remaining three are so hard to break.
The Dorabella Cipher
The Dorabelle Cipher is an 87-glyph, three-line code. It has been written by composer Edward Elgar in a letter he had sent to Dora Penny in 1897. Elgar was a huge passionate of cryptography; he often stated that his compositions hid coded references to other famous works. There have been many attempts made to break the Dorabella Chiper, but even now, 117 years later, it remains unsolved.
The Voynich Manuscript might be one of the most famous unsolved texts in history. It was named after Wilifred M. Voynich, the book dealer who managed to acquire the manuscript in 1912. The manuscript is made of approximately 240 pages of unidentified plants, herbal recipes, astronomic diagrams and weird anatomic drawings. The language used for the Voynich Manuscript remains a mystery even today. Nobody knows what purpose this book held and what mysteries it contains. All we know is that it is dated back to the 15th century.
