Hybrid

The Bifid–Bacon Hybrid cipher is a composite classical cipher that combines the fractionation principles of the Bifid cipher, invented by Félix Delastelle in 1901, with the binary encoding approach of the Baconian cipher, developed by Francis Bacon in 1605. This hybrid system leverages both numerical fractionation and letter-to-binary substitution to increase diffusion and obscure the relationship between plaintext letters and ciphertext symbols.

A Combination Cipher, also known as a Mixed Alphabet Cipher, is a type of encryption technique that combines elements of different encryption methods. It is a substitution cipher where each character in the plaintext is replaced by a character from a different alphabet or set of symbols.

The Combination Cipher typically involves multiple encryption steps using different substitution rules or alphabets. This creates a more complex and secure encryption scheme by combining the strengths of different cipher techniques.

Cicada 3301 is a mysterious and enigmatic online puzzle or alternate reality game that gained notoriety for its complexity and anonymity. It first appeared in January 2012 with a series of cryptic puzzles and challenges, often posted on various internet forums and websites.

The puzzles typically involve a combination of cryptography, steganography, computer programming, and knowledge of various disciplines. Solving these challenges often requires a deep understanding of diverse subjects and analytical skills.
