In a Substitution cipher, any character of plain text from the given fixed set of characters is substituted by some other character from the same set depending on a key. For example with a shift of 1, A would be replaced by B, B would become C, and so on.

WebMar 7, 2024 · Video. The Affine cipher is a type of monoalphabetic substitution cipher, wherein each letter in an alphabet is mapped to its numeric equivalent, encrypted using a simple mathematical function, and converted back to a letter. The formula used means that each letter encrypts to one other letter, and back again, meaning the cipher is essentially ... WebTypes of Cipher. Several types of cipher are given as follows: 1. Caesar Cipher. In Caesar cipher, the set of plain text characters is replaced by any other character, symbols, or numbers. It is a very weak technique for hiding text. In Caesar’s cipher, each alphabet in the message is replaced by three places down. jared warren photography

In cryptography, a transposition cipher (also known as a permutation cipher) is a method of encryption which scrambles the positions of characters (transposition) without changing the characters themselves. Transposition ciphers reorder units of plaintext (typically characters or groups of characters) according to a regular system to produce a ciphertext which is a permutation of the plaintext. They differ from substitution ciphers, which do not change the position of units …
