Despite his astrology-related penname the killer hadn't shown any clear interest in astrology, and it's possible he drew inspiration from previous killers such as Jack the Ripper. These letters included four cryptograms or ciphers, two of which have yet to be solved. The first use of the term "cryptograph" (as opposed to "cryptogram") dates back to the 19th century—originating from "The Gold-Bug," a story by Edgar Allan Poe. Until modern times, cryptography referred almost exclusively to "encryption", which is the process of converting ordinary information (called plaintext) into an unintelligible form (called ciphertext). Decryption is the reverse, in other words, …

WebPolyalphabetic cipher. A polyalphabetic cipher substitution, using multiple substitution alphabets. The Vigenère cipher is probably the best-known example of a polyalphabetic cipher, though it is a simplified special case. The Enigma machine is more complex but is still fundamentally a polyalphabetic substitution cipher. WebThe affine cipher is a type of monoalphabetic substitution cipher, where each letter in an alphabet is mapped to its numeric equivalent, encrypted using a simple mathematical function, and converted back to a letter.The formula used means that each letter encrypts to one other letter, and back again, meaning the cipher is essentially a standard substitution …

[1] The pigpen cipher (alternatively referred to as the masonic cipher, Freemason's cipher, Napoleon cipher, and tic-tac-toe cipher) [2] [3] is a geometric simple substitution cipher, which exchanges letters for symbols which are fragments of a grid.
WebCryptograms are puzzles where the words or sentences have been encoded. A substitution method is commonly used, where each letter is replaced by a different letter or number. Your job is to crack the code and discover the original lettering to reveal the hidden message. WebRunning key cipher. In classical cryptography, the running key cipher is a type of polyalphabetic substitution cipher in which a text, typically from a book, is used to provide a very long keystream. Usually, the book to be used would be agreed ahead of time, while the passage to be used would be chosen randomly for each message and secretly ...
