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), ...
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]. ...

对称密钥算法(Symmetric-key algorithm),又称为对称加密、私钥加密、共享密钥加密,是密码学中的一类加密算法。 对称加密的特点是,在加密和解密时使用相同的密钥,或是使用两个可以简单地相互推算的密钥。 这一个或一组密钥需要在两个或多个成员之间共享,以便维持专属的通讯联系。 对称加密的优点是速度快,缺点是需要共...
