Mystery Codes that Still have not been deciphered

There are several mysteries and riddles people create. Some create them to hide their secrets, some use them to hide other secrets, some use them to hide treasure and others create them just to test people’s riddle solving abilities. The ones listed below are some of the most examined, yet, still unsolved mysteries.

Image #: 12705752 Kryptos is a sculpture by American artist Jim Sanborn located on the grounds of the Central Intelligence Agency (CIA) in Langley, Virginia. Since its dedication on November 3, 1990, there has been much speculation about the meaning of the encrypted messages it bears. Of the four sections, three have been solved, with the fourth remaining one of the most famous unsolved codes in the world. The sculpture continues to provide a diversion for some employees of the CIA and other cryptanalysts attempting to decrypt the messages. MAI /Landov It’s like a tease, standing outside the headquarters of the CIA in daily view of some of the nation’s brightest cryptographers yet eluding them for years. The Krytpos monument is a sculpture by artist Jim Sanborn bearing an encrypted message divided into four sections, three of which have been solved since its installation in 1990. With misspellings in the code intact, the first part reads, “Between subtle shading and the absence of light lies the nuance of iqlusion”, and the second part references some invisible buried treasure ostensibly located some 200 feet from the statue itself.

Taman Shud Case
SomertonManCode Who was the Somerton man, how did he die, and what do these strange codes found on a book connected to the man mean? An unidentified male body was found on Somerton Beach in Adelaide, Australia in 1948 wearing a sweater and coat despite the hot day, carrying no identification. There were no clues as to his identity and dental records and fingerprints matched no living person. An autopsy discovered bizarre congestion, blood in the stomach and enlarged organs but no foreign substances. A suitcase found at the train station that may have belonged to the man contained a pair of trousers with a secret hidden pocket, which held a piece of paper torn from a book imprinted with the words “Taman Shud”. The paper was matched to a very rare copy of Omar Khayyam’s ‘The Rubaiyat’ that was found in the backseat of an unlocked vehicle and on the back of the book was scrawled five lines of capital letters that seem to be a code. To this day, the entire case remains one of Australia’s most bizarre mysteries.

Georgia Guidestones
Georgia_Guidestones-lowres The Georgia Guidestones is a granite monument erected in 1980 in Elbert County, Georgia, in the United States. A set of 10 guidelines is inscribed on the structure in eight modern languages, and a shorter message is inscribed at the top of the structure in four ancient language scripts: Babylonian, Classical Greek, Sanskrit, and Egyptian hieroglyphs. The monument stands at the highest point in Elbert County, about 90 miles east of Atlanta, 45 miles from Athens, and 9 miles north of the center of Elberton. The stones are visible from Georgia Highway 77 and are reached by turning east on Guidestones Road. The structure is sometimes referred to as an “American Stonehenge”. The monument is 19 feet 3 inches tall, made from six granite slabs weighing 237,746 pounds in all. One slab stands in the center, with four arranged around it. A capstone lies on top of the five slabs, which are astronomically aligned. An additional stone tablet, which is set in the ground a short distance to the west of the structure, provides some notes on the history and purpose of the Guidestones.

The Zodiac Killer’s Alphabet
340cipher The Zodiac Killer – whoever he is or was – is known just as much for the incredibly complex coded letters he sent to the Bay Area press as for his brutal unsolved murders. While some of his taunting ciphers have been solved, this 340-character message sent in 1969 has never been cracked.

Dorabella Cipher
dorabella-cipher-image Sent by cipher enthusiast Edward Elgar to his friend Miss Dora Penny, the Dorabella Cipher seems upon viewing like it might not mean anything at all. But this string of strange symbols, made up of semicircles in various configurations, has been the subject of unfruitful study for over a century. Musicologist Eric Sams claimed to have solved it, but his methods are unproven and his translation is 22 characters longer than the cipher. Another speculation is that the code is not text, but a melody.

permute If an autobiography detailing the author’s memories of James Joyce seems like a strange place to find an uncracked cipher, that’s because it is. J.F. Byrne inserted his cryptosystem challenge into the book “Silent Years”, offering $5,000 to whoever solved it. At least three people know how Byrne’s Chaocipher – a machine small enough to fit into a cigar box used to encrypt the message – actually works, but no one has ever solved the code.

D’Agapeyeff Cipher
The-esoteric-text-known-as-DAgapeyeff-cipher-has-yet-to-be-decoded Alexander d’Agapeyeff wasn’t even a cryptographer – having previously written a book on cartography, he decided to tackle cryptography in his second book, “Codes and Ciphers”, in 1939. On the last page of the book, he included a modest cryptogram “upon which the reader is invited to test his skill.” But modest or not, d’Agapeyeff’s code has remained uncracked for 70 years, putting this amateur into the same league as the world’s most gifted cryptographers.

The Beale Papers
Beale_Papers Want $40 million in buried gold, silver and jewels? All you have to do is solve an infamously “impossible” set of ciphertexts, one of which effectively provides that much-sought X on the map. The treasure was reputedly buried in Bedford County, Virginia by one Thomas Jefferson Beale, who entrusted his encrypted ciphertexts to a local innkeeper. After the innkeeper’s death, a friend who was given the papers spent twenty years trying to solve the ciphers, finally completing the one that describes the treasure. Despite many tries, the two others have never been solved.

Shugborough Inscription
Shugborough_inscription_D_OUOSVAVV_M O-U-O-S-V-A-V-V. These letters are carved into a stone monument directly below a mirror image of Nicholas Poussin’s painting, The Shepherds of Arcadia, on the grounds of Shugborough Hall in Staffordshire, England – but what do they mean? Popular fiction imagines that Poussin was a member of the Priory of Scion and that the inscription refers to the location of the Holy Grail, but nobody really knows. Perhaps they’re an acronym for Orator Ut Omnia Sunt Vanitas Ait Vanitas Vanitatem, a version of the biblical phrase “Vanity of vanities, saith the preacher, all is vanity” – but perhaps not.

Chinese Gold Bar Cipher
uncracked-chinese-gold-bar-cipher The images seem to show a series of gold bars covered in images, strange symbols, Chinese writing, an unidentified script and crytpograms in Latin letters. These gold bars were supposedly issued to a General Wang in Shanghai, China and deposited into a U.S. bank in 1933, but they’re so strange, the validity of the deposit is still disputed today. If someone can solve the script and codes, the dispute could be settled. Large images of all seven bars can be viewed at

Phaistos Disc
phaistosdiscs From WebUrbanist’s “10 Most Amazing Ancient Objects of Mystery in History”: “There’s very little that we actually know for sure about the Phaistos Disc. It’s made of clay – check. It dates back to the second millennium B.C.E. – maybe. But its origin, meaning and purpose remain shrouded in mystery. Discovered in Crete, the disc is features i241 impressions of 45 distinct symbols, some of which are easily identifiable as people, tools, plants and animals. But because nothing else like it from the same time period has ever been found, archaeologists haven’t been able to provide a meaningful analysis of its content.”

Voynich Manuscript
voynich_manuscript613c Purchased by book dealer Wilfrid Voynich in 1912, the 240-page Voynich manuscript has been labelled one of the world’s most mysterious manuscripts. It consists of six distinct sections, containing undecipherable text alongside herbal, astronomical, biological, cosmological and pharmaceutical illustrations.The text uses over 170,000 symbols and displays statistical properties akin to that of natural languages. While further statistical analyses point towards the manuscript being a hoax, it is generally considered that it is too elaborate for this to be the case. Either way, the Voynich manuscript has attracted the attention of many cryptanalysts over the years, most notably the military cryptanalyst William Friedman.
