The code above only supports 128bit of plaintext encryption which is a block cipher of AES algorithm. If your plaintext is more than that there are several ways(AES modes) to encrypt data, such as ECB (Electronic Code Book), CBC (Cipher Block Chaining), CFB (Cipher Feedback), For deta...

The encryption algorithm performs a preliminary processing step that's called AddRoundKey in the specification. AddRoundKey performs a byte-by-byte XOR operation on the State matrix using the first four rows of the key schedule, and XORs input State[r,c] with round keys table w[c,r]. ...

Substitution Boxes play a vital role in the Rijndael algorithm of modern block ciphers. The security and efficiency of these ciphers mainly depend upon the algebraic construction of their Substitution Boxes. In this paper, the algebraic construction of the Substitution Boxes for the AES algorithm is...
