There are basically two types of symmetric cipher: Substitution Cipher, Transposition Cipher.

Substitution Cipher: A substitution is a technique in which each letter or bit of the plaintext is substituted or replaced by some other letter, number or symbol to produce cipher text. For Example, ABC ⟹ XYZ.

Types of Substitution Cipher: Caesar Cipher, Monoalphabetic Cipher, Vigenère Cipher, Playfair Cipher, One time pad cipher (Vernam cipher), Hill Cipher.

Transposition Cipher: In transposition technique, there is no replacement of alphabets or numbers occurs instead their positions are changed or reordering of position of plain text is done to produce cipher text. For Example, ABCDE ⟹ BADEC.

Types of Transposition Cipher: Rail Fence Cipher, Columnar Transposition Cipher.

In this video, I have explained Caesar cipher with example. Caesar cipher is type of substitution cipher. This technique was found by Julius Caesar. This technique is very simple and easy to generate cipher of given plain text. This technique is also known as shift cipher. In Caesar cipher techniques each letter/alphabet is replaced by the letter/alphabet which is three place next to the letter which is to be substituted. (Three place next to the letter method was used by Julius Caesar.)
