CBC(Cipher Block Chaining)是一种数据加密模式,是一种对称加密的工作模式。在CBC模式中,每个明文块都需要与前一个密文块进行异或运算后再进行加密,增加了数据的随机性和安全性。 步骤2: 在MySQL中使用AES_ENCRYPT进行加密操作 -- 创建一个表存放加密后的数据CREATETABLEencrypted_data(idINTPRIMARYKEYAUTO_INCREMENT,...

解密的时候,第一个块解密使用的是Initialization Vector进行异或操作,后续的块解密使用的是前一个块的密文来进行异或操作,也就是说CBC模式加密解密是前后文关联的。 CTR模式观察下图: CTR模式与CBC模式相比,不同的地方在于,进行AES解密的时候,使用的是一个Counter来进行AES加密,Counter的初始值就是Initialization Vector...

But now I would like to actually encrypt/decrypt data. The two functions are assembly routines found in /crypto/aes/aesni-x86_64.s, actually. I'm just a bit burned out from reading more code. I'm looking for the direct functions that just do the encryption using the AES_256_CBC ciph...
I want to encrypt (or decrypt) large file. It is unreasonable/impossible to load the whole file into memory and process it by single AESEncryptCBC call. The more affordable way is to process that file using consecutive smaller chunks. So, as far as I understand, the term "initialization ...
