CBC mode The CBC (Cipher Block Chaining) mode (Fig. 2) provides this by using an initialization vector – IV. The IV has the same size as the block that is encrypted. In general, the IV usually is a random number, not a nonce. We can see it in figure 2, the plaintext is divide...

对称加密aes128 1.对称加密算法对称加密是最快速、最简单的一种加密方式,加密(encryption)与解密(decryption)用的是同样的密钥(secret key)。对称加密有很多种算法,由于它效率很高,所以被广泛使用在很多加密协议的核心当中。对称加密通常使用的是相对较小的密钥,一般小于256 bit。因为密钥越大,加密越强,但加密与解密...
