Shugborough Inscription
The Shugborough Inscription is a sequence of letters – O U O S V A V V, between the letters D M on a lower plane – carved on the 18th-century Shepherd's Monument in the grounds of Shugborough Hall in Staffordshire, England, below a mirror image of Nicolas Poussin's painting the '' Shepherds of Arcadia''. It has never been satisfactorily explained, and has been called one of the world's top uncracked ciphertexts. In 1982, the authors of the pseudohistorical ''The Holy Blood and the Holy Grail'' suggested that Poussin was a member of the Priory of Sion, and that his ''Shepherds of Arcadia'' contained hidden meanings of great esoteric significance. The book makes a passing reference to the Shepherd's monument and the inscription, but offers no solution. In 2003, Dan Brown copied many elements of ''The Holy Blood and the Holy Grail'' in his bestselling novel ''The Da Vinci Code'', but made no mention of the Shugborough inscription. However, the book led to renewed interest in ''Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
11B-X-1371
''11B-X-1371'' is an early-2015 viral video sent to GadgetZZ.com, the Swedish tech blog that publicized it. The black-and-white segment is two minutes in length; its title came from the plaintext of a base64 string written on the DVD. It depicts a person wearing what appears to be a plague doctor costume walking and standing around in a dilapidated abandoned building, with a forest visible through former window openings in the wall behind it. Accompanied by a soundtrack of loud, discordant buzzing noise, the masked figure holds up a hand with an irregularly blinking light. The film did not have any credits or claims to authorship. Messages, many in commonly used ciphers and encryption systems, have been found hidden in the video and its sound spectrogram, as well as images of tortured and mutilated people. Most of the messages have been decoded by participants in an ongoing Reddit thread, and the images sourced to notable murder investigations such as the Boston Strangler. They h ...

Cicada 3301
Cicada 3301 is a nickname given to three sets of puzzles posted under the name "3301" online between 2012 and 2014. The first puzzle started on January 4, 2012, on 4chan and ran for nearly a month. A second round began one year later on January 4, 2013, and then a third round following the confirmation of a fresh clue posted on Twitter on January 4, 2014. The third puzzle has yet to be solved. The stated intent was to recruit "intelligent individuals" by presenting a series of puzzles to be solved; no new puzzles were published on January 4, 2015. A new clue was posted on Twitter on January 5, 2016. Cicada 3301 posted their last verified OpenPGP-signed message in April 2017, denying the validity of any unsigned puzzle. The puzzles focused heavily on data security, cryptography, steganography, and internet anonymity. It has been called "the most elaborate and mysterious puzzle of the internet age", and is listed as one of the "top 5 eeriest, unsolved mysteries of the internet" by '' ...

The Da Vinci Code
''The Da Vinci Code'' is a 2003 mystery thriller novel by Dan Brown. It is Brown's second novel to include the character Robert Langdon: the first was his 2000 novel ''Angels & Demons''. ''The Da Vinci Code'' follows symbologist Robert Langdon and cryptologist Sophie Neveu after a murder in the Louvre Museum in Paris causes them to become involved in a battle between the Priory of Sion and Opus Dei over the possibility of Jesus Christ and Mary Magdalene having had a child together. The novel explores an alternative religious history, whose central plot point is that the Merovingian kings of France were descended from the bloodline of Jesus Christ and Mary Magdalene, ideas derived from Clive Prince's ''The Templar Revelation'' (1997) and books by Margaret Starbird. The book also refers to ''The Holy Blood and the Holy Grail'' (1982) though Dan Brown has stated that it was not used as research material. ''The Da Vinci Code'' provoked a popular interest in speculation concerning ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Smithy Code
The Smithy code is a series of letters embedded, as a private amusement, within the April 2006 approved judgement of Peter Smith (judge), Mr Justice Peter Smith on ''The Da Vinci Code'' copyright case. It was first broken, in the same month, by Dan Tench, a lawyer who writes on media issues for ''The Guardian'', after he received a series of email clues about it from Justice Smith. How the code works The letters in question are part of the actual text of the judgement, but italicised in contrast to the rest of the text. The following sequence of unusually emphasised letters can be extracted from the judgement document: The italicised letters only occur up to paragraph 43 (which is page 13 of a 71-page document). Meanwhile, paragraph 52 concludes with this sentence: "The key to solving the conundrum posed by this judgment is in reading HBHG and DVC." (These abbreviations are used by Smith throughout the judgement in referring to the books at issue, ''The Holy Blood and the Holy ...

Ricky McCormick's Encrypted Notes
Two hand-written documents were found in the pockets of murder victim Ricky McCormick when his body was discovered in a field in St. Charles County, Missouri on June 30, 1999. Attempts by the FBI's Cryptanalysis and Racketeering Records Unit (CRRU) and the American Cryptogram Association failed to decipher the meanings of those two coded notes, which are listed as one of the CRRU's top unsolved cases. On March 29, 2011, the U.S. Federal Bureau of Investigation issued an appeal for help from the public in obtaining the meaning of the messages. A few days later, they updated their website to note the "outpouring of responses", and established a separate page where the public can offer comments and theories. Murder Victim Ricky McCormick was a high school dropout who had held multiple addresses in the Greater St. Louis area, living intermittently with his elderly mother. According to a 1999 article in the ''St. Louis Post-Dispatch'', McCormick suffered from chronic heart and lun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kryptos
''Kryptos'' is a sculpture by the 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 four encrypted messages it bears. Of these four messages, the first three have been solved, while the fourth message remains one of the most famous unsolved codes in the world. The sculpture continues to be of interest to cryptanalysts, both amateur and professional, who are attempting to decipher the fourth passage. The artist has so far given four clues to this passage. Description The main part of the sculpture is located in the northwest corner of the New Headquarters Building courtyard, outside of the Agency's cafeteria. The sculpture comprises four large copper plates with other elements consisting of water, wood, plants, red and green granite, white quartz, and petrified wood. The most prominent feature is a large vertical S-s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Magic Words Are Squeamish Ossifrage
"The Magic Words are Squeamish Ossifrage" was the solution to a challenge ciphertext posed by the inventors of the RSA cipher in 1977. The problem appeared in Martin Gardner's ''Mathematical Games column'' in the August 1977 issue of ''Scientific American''. It was solved in 1993–94 by a large, joint computer project co-ordinated by Derek Atkins, Michael Graff, Arjen Lenstra and Paul Leyland. More than 600 volunteers contributed CPU time from about 1,600 machines (two of which were fax machines) over six months. The coordination was done via the Internet and was one of the first such projects. ''Ossifrage'' ('bone-breaker', from Latin) is an older name for the bearded vulture, a scavenger famous for dropping animal bones and live tortoises on top of rocks to crack them open. The 1993–94 effort began the tradition of using the words "squeamish ossifrage" in cryptanalytic challenges. The difficulty of breaking the RSA cipher—recovering a plaintext message given a ciphertext a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zodiac Killer
The Zodiac Killer is the pseudonym of an unidentified serial killer who operated in Northern California in the late 1960s. The case has been described as the most famous unsolved murder case in American history. It became a fixture of popular culture and inspired amateur detectives to attempt to solve it. The Zodiac murdered five known victims in the San Francisco Bay Area between December 1968 and October 1969, operating in rural, urban and suburban settings. He targeted young couples and a lone male cab driver. His known attacks took place in Benicia, Vallejo, unincorporated Napa County, and the city of San Francisco proper. Two of his wounded victims survived. The Zodiac claimed to have murdered 37 victims. He has been linked to several other cold cases, some in Southern California or outside the state. The Zodiac coined this name in a series of taunting letters and cards that he mailed to regional newspapers, in which he threatened killing sprees and bombings if they were ...

Tamam Shud Case
The Somerton Man was an unidentified man whose body was found on 1 December 1948 on the beach at Somerton Park, South Australia, Somerton Park, a suburb of Adelaide, South Australia. The case is also known after the Persian language, Persian phrase (Persian: تمام شد), meaning "is over" or "is finished", which was printed on a scrap of paper found months later in the Besom pocket, fob pocket of the man's trousers. The scrap had been torn from the final page of a copy of ''Rubaiyat of Omar Khayyám'', authored by 12th-century poet Omar Khayyám. Following a public appeal by police, the book from which the page had been torn was located. On the inside back cover, detectives read through indentations left from previous handwriting: a local telephone number, another unidentified number, and text that resembled a Cryptography, coded message. The text has not been deciphered or interpreted in a way that satisfies authorities on the case. The case has been considered, since the ...

Lorenz Cipher
The Lorenz SZ40, SZ42a and SZ42b were German rotor stream cipher machines used by the German Army during World War II. They were developed by C. Lorenz AG in Berlin. The model name ''SZ'' was derived from ''Schlüssel-Zusatz'', meaning ''cipher attachment''. The instruments implemented a Vernam stream cipher. British cryptanalysts, who referred to encrypted German teleprinter traffic as ''Fish'', dubbed the machine and its traffic ''Tunny'' (meaning tunafish) and deduced its logical structure three years before they saw such a machine. The SZ machines were in-line attachments to standard teleprinters. An experimental link using SZ40 machines was started in June 1941. The enhanced SZ42 machines were brought into substantial use from mid-1942 onwards for high-level communications between the German High Command in Wünsdorf close to Berlin, and Army Commands throughout occupied Europe. The more advanced SZ42A came into routine use in February 1943 and the SZ42B in June 1944. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
