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.

The rail fence cipher (sometimes called zigzag cipher) is a transposition cipher that jumbles up the order of the letters of a message using a basic algorithm. It is one of the easy techniques of transposition cipher in which position of letters are changed. The rail fence cipher works by writing your message on alternate lines across the page, and then reading off each line in turn. Note that all white spaces have been removed from the plain text
