Encryptions

The Grid Transposition Cipher is a method of encryption that involves rearranging the characters of a message based on a predetermined grid pattern. It is a type of transposition cipher, where the original letters of the plaintext are maintained, but their positions are altered to create the ciphertext.

The Dorabella Cipher is a mysterious and elegant encrypted message created by English poet Edward Elgar for a close friend, Dora Penny, in 1897. It is a substitution cipher, a type of code where each letter in the plaintext is replaced with a different letter or symbol to conceal the original message.

A Digraph Cipher is a cryptographic technique that operates on pairs of letters (digraphs) rather than individual letters. It is a substitution cipher where each digraph in the plaintext is replaced by a corresponding digraph in the ciphertext according to a predefined rule or key.

Here's a general overview of how a Digraph Cipher works:

A Dice Cipher, also known as a Dice Cryptography or a Book Cipher, is a cryptographic technique that uses dice as a randomization tool to generate a series of numbers that correspond to words or characters in a pre-selected reference book. It is a form of polyalphabetic substitution cipher.

Here's a general overview of how a Dice Cipher works:

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.

The Columnar cipher is a transposition cipher that rearranges the characters of a message by writing them in a grid format and then reading them column by column in a specific order. It does not change the actual characters but alters their order to create the ciphertext.

Here's how the Columnar cipher works:

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.

A book cipher is a method of encryption and decryption that employs a physical book or text as the key. In this technique, secret messages are concealed by referencing specific words or passages from the book to encode and decode information. To encrypt a message, each word in the plaintext is replaced with a corresponding word or phrase found at a predetermined location within the chosen book.
