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...

MAC 全称是 Message Authentication Code,中文名称为消息认证码,一串由密钥和密文生成的固定值,有时也称 Auth Tag。 MAC 的使用流程如下: 首先Sender 和 Receiver 共享同一个 Key,约定一个 MAC 计算算法 Algorithm Sender 把要传递的消息 Message 通过 Key 和 Algorithm 计算出 MAC,将 Message 和 MAC 发送给 Rece...

In this program, you are required to demonstrate the AES-256-CBC algorithm with a third-party crypto library, pycryptodome. Recall that you must provide a corresponding requirements.txt file if any third party libraries are involved in the code. Your program does the following: Read a text str...
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]. ...
Now that we know what the AES algorithm is supposed to do, let's see what its implementation looks like as a vertex program. The code given throughout this chapter uses C-style macros and comments to improve readability of the assembly language. These—like those in theROT8macr...
29 * AES is an encryption standard based on Rijndael algorithm, a symmetric block30 * cipher that can process data blocks of 128 bits, using cipher keys with31 * lengths of 128, 192, and 256 bits. Refer to FIPS 197 for more details...
