The Vigenère Cipher is a classical cryptographic method that enhances the security of simple substitution ciphers. It was developed by the French diplomat Blaise de Vigenère in the 16th century.
The Trifid Cipher is a cryptographic technique that combines elements of substitution and transposition ciphers to encrypt messages. It was invented in 1901 by Félix Delastelle, a French cryptographer, and is known for its use of three-dimensional representations.
The Templar Cipher is a cryptographic method associated with the Knights Templar, a medieval Christian military order founded during the Crusades. It is one of the many historical ciphers that have been attributed to the Knights Templar, although the exact cipher they used remains a subject of debate and speculation.
The Polyalphabetic Cipher is a type of substitution cipher that enhances the security of traditional ciphers by introducing multiple alphabets or cipher alphabets. In this encryption technique, each letter of the plaintext is substituted with a corresponding letter from one of several different cipher alphabets, based on a secret key or keyword.
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.
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 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.
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.
