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.
Hill Cipher is polyalphabetic substitution cipher. This technique was developed by mathematician Laster Hill. Hill cipher based on linear algebra. Input of this technique are keyword and plain text. Keyword is given in matrix form.
In this video, I have explained hill cipher encryption and decryption rules with example. Also explained hill cipher example of 2x2 keyword matrix encryption and decryption. Explaine example of 3x3 keyword matrix encryption.

Thanks for the explanation. I have a question, what if it is given that A does not start with 0 but any random number like 17? Do we still do mod 26 and add 17 to the final answer to find the corresponding alphabet?

You should assign any number to any character (does not repeat number)...Process of encryption and decryption will be same....but you must check that table of A...Z (assigned number) is same during encryption and decryption....It should not be changed...
@@ChiragBhalodia Thanks for the reply sir 👍
You are welcome
Best explained sir

how can we encrypt if the key of hill cipher is not a square matrix like plaintext="alphabets" and key="cryptography"
You have to given alphabets put in a 3x3 matrix and put a value infornt of character.

Hey what to do if there's whitespaces in the plain text?
If there is white space in plain text, you can cosider the value of white space and then you can calculate....
understand able👍

what if the plain text is 5 letters? (in 2x2 matrix)
You can add letter "Z" to make a pair with last character...

@@ChiragBhalodia what if 7letters and given matrix is 3x3 ??? Pls reply sir
You can add ZZ as last two characters...
SEJZUS right?
Correct....!!! Also try 2nd Example...

Plain text : pay
3*3 encryption and decryption value answer video potunga sir
Please
17 17 5
21 18 21
2 2 19
Intha value ku video potunga sir
Encyption is easy as per video.... but I cannot make a video of decryption because it takes much time in calculation due to inverse matrix calculation.
IS THE ANSWER SEHWXW
Fow which exercise 1 or 2????? By the way your answer is wrong for both exercises... Try again tell me in comment. If again wrong I will give you the final answer with solution.
It’s SEJZUS for exercise 1 and FEMEFV for exercise 2
Yes....Your answer is absolutely right....
