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.

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.
