Null Cipher

Tags

The Null Cipher, also known as the Null Encryption or Null Message, is a simplistic cryptographic technique where specific letters or symbols are deliberately left blank or null in a message. Instead of using complex algorithms or substitutions, the Null Cipher relies on the absence of characters to convey hidden information.

Map Cipher

Tags

The Map Cipher, also known as the Route Cipher or Matrix Cipher, is a method of encryption that involves rearranging characters of a message according to a predefined route or pattern on a grid or map. It is a type of transposition cipher, where the original letters of the plaintext are preserved, but their order is changed to create the ciphertext.

Keyboard Code

Tags

Keyboard Code, also known as Keyboard Cipher or Keyboard Encryption, is a simple and straightforward method of encrypting and decrypting messages using a keyboard layout as a reference. It is a type of substitution cipher, where each letter of the plaintext is replaced with a corresponding letter from the keyboard layout.

Grid Transposition Cipher

Tags

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.

Giovanni Fontana Cipher

Tags

The Giovanni Fontana Cipher, attributed to the Italian engineer and writer Giovanni Fontana in the 15th century, is an early example of a cryptographic method known as a homophonic substitution cipher.

Francis Bacons Substitution Cipher

Tags

Francis Bacon's Substitution Cipher is an ingenious cryptographic technique devised by the English philosopher and statesman Sir Francis Bacon in the late 16th and early 17th centuries. It is a form of steganography, a method of concealing secret messages within seemingly ordinary text.

Dorabella Cipher

Tags

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.

Digraph Cipher

Tags

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:

Dice Cipher

Tags

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:

Combination Cipher

Tags

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.
