Ciphers exist to hide valuable information and maintain a secret. And if you manage to unravel what is written, then you can find out the secret of a person, the coordinates of a treasure, or even the history of an entire civilization. But there are messages that remain unsolved for centuries.

website I have collected for you 9 of the most mysterious and unusual encrypted messages, behind which something great is probably hidden.

No. 1. Codex Serafini

A book written in the late 70s by the Italian architect Luigi Serafini. This is a 360-page atlas of a fictional world, painted down to the smallest detail (fauna, architecture, laws of nature, history, languages, entertainment).

But the main mystery is that the code is handwritten in cipher text, which no one has been able to solve. Although the author of the book is still alive, he flatly refuses to say whether it is even a real language. There is a version that the book conveys the child’s worldview. and try to understand it.

No. 2. Messages of the Zodiac

Zodiac is an elusive serial killer who terrorized all of San Francisco in 1968–1969.

He claimed that his real name could only be found out if all 4 parts of the code he sent to the police station were read. As a result, detectives were able to decipher only 3 parts. The last 18 characters remain a mystery. Perhaps that's where the killer's name is written.

No. 3. Bale cryptograms

In 1822, a certain Thomas Jefferson Bale gave a box and a key to the owner of a hotel and told him to keep it carefully. After which Bale disappeared without a trace. The box was opened only in 1843. Inside were three sheets of paper with encryption and content signatures. The first note contained the coordinates, the second - the contents of the cache, and the third - the names of the heirs.

It was possible to decipher only the second note. It spoke of "three wagons of gold" located in Virginia somewhere in Bedford County. In modern terms, the treasure is worth $30 million. The remaining two notes with exact coordinates have never been read by anyone.

No. 4. Dorabella cipher

English composer and cryptologist Edward Elgar sent a coded message (87 characters) to his friend Dorabella Penny in 1897. The note contains symbols that look like springs. However, the girl was never able to figure it out.

No. 5. Kryptos

Kryptos- a copper sculpture that stands near the CIA headquarters in Langley, Virginia. Artist James Sanborn in 1990 placed a message on the sculpture, which he encrypted on 4 plates. At the same time, Sanborn noted that the message can only be read when all 4 parts are solved.

Today the meaning of 3 out of 4 sections is known. The most experienced cryptographers have been struggling unsuccessfully over the meaning of the last 97 characters for 20 years.

No. 6. Encryption from Shaboro

In Staffordshire (Great Britain) there is an 18th-century monument that reflects the events of Nicolas Poussin’s painting “The Shepherds of Arcadia”. If you look closer, you can see on the monument a strange sequence of letters DOUOSVAVVM - a code that no one has been able to decipher for more than 250 years.

Many people tried to find out the answer to the riddle, including Charles Darwin and Charles Dickens, but without success. Some cryptographers believe that the code may be a clue left by the Templars about the location of the Holy Grail.

No. 7. General Wang's gold bars

In 1993, General Wang from Shanghai received an unusual parcel - 7 gold bars, each of which had encoded inscriptions. The cipher on the bullion consists of Chinese characters and cryptograms in Latin.
