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.
Playfair cipher is type of substitution cipher. It is also called polyalphabetic substitution cipher. In this cipher techniques, more than one character is used during encryption/decryption. So, this cipher technique is called multiple substitution cipher technique. Input of this technique are keyword and plain text. Keyword is one type of string.

What if it is IJ?

[@ChiragBhalodia]

1. If there is "I" in key, you must put "I" in matrix. Then there is "J" in plain text, you can take "I" as "J" from key matrix.

What about JK?

[@ChiragBhalodia]

You can use either "I" or "J"... If you have created matrix with "I" instead of "J". Then you are going to encrypt the word, you will get "J" in any of the pair of plain text. You will consider "I" instead of "J".

@@ChiragBhalodia okk...but what if there will be IJ?

[@ChiragBhalodia]

for exapmle, plain text = IJT. there is one pair in plain text "IJ".... So you have to write "I" instead of "J".... So our pair will be "II"....As per the rule, if two characters are same in pair then pair will be written as "IX" (First pair of plain text)and "IT" (second pair of plain text). (Follow the step-3 --> possibility-2...... Check in my blog....blog link is given below.)
