Matrix

A Transposition Cipher is a type of cryptographic method that encrypts messages by rearranging the characters or symbols of the plaintext without altering the original letters themselves. Instead of replacing letters with different symbols (as in substitution ciphers), transposition ciphers focus on changing the order of the characters to conceal the message.

The Spiral Cipher is a method of encrypting messages by arranging the plaintext in a spiral pattern, typically on a grid or matrix. It is a type of transposition cipher, where the original letters of the message are preserved but rearranged in a specific order.

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.
