Plaintext would be extended with padding to have right size. Plaintext is rarely right size for AES it is very common it requires padding to be some multiplication of 128bits
@@GamingWithSamiCheema Take it with a grain of salt, but my understanding is that it will be extended for example to August\x0A\x0A\x0A\x0A\x0A\x0A\x0A\x0A\x0A\x0A. (You just added 10x x0A Byte at the end of it to extend August which was 6 bytes to 16bytes) It depends on the type of padding which will be used there are different types. This one is for example is defined by PKCS7. Padding is usually just repeatedly adding some specific bits just to make message longer so it fits the required bit length. Then you have right length for plaintext and you can encrypt it with AES block cipher. When decryption happens you still will have plaintext with padding and you have to also remove it afterwards to get purely message.

👏🏻🫡
You are a life saver! Thank you so much. What was taught by my professor in 4 hrs, took you 10 mins. So concise and straight to the point :)
Dear neso ,could you help me out by implementing AES,RSA algorithm,and other substitution techniques , in C c++ or java
What to do , if we have Key or plaintext other than 128 or 192 or 256 bits??? What if plain text is less than 128 bits?

@@tonnytrumpet734what is padding?
For example, we have key as:
August
So how to complete it to 16 bytes

Thanks big dawg
Pls make a vedio on this topic: Blow fish RC -5 Algorithm..
clear and logically sound !!
