Some content-encryption algorithms assume the input length is a multiple of k octets, where k > 1, and let the application define a method for handling inputs whose lengths are not a multiple of k octets. For such algorithms, the method shall be to pad the input at the trailing end wit...
为了方便自己,后来写了一个密码管理系统,用到了AES加密相关知识,对自己帮助挺大的,分享一下这块技术。 一、什么是AES 高级加密标准(AES,Advanced Encryption Standard),是一种最常见的对称加密算法,AES在世界各地的软件和硬件中实施加密敏感数据。 AES的加密流程介绍 1.明文P:没有经历加密的数据 2.密钥K:用来加密...
我在这里只进行简单的说明,AES是advanced encryption standard,是一种加密的方式。通常用来在数据传输之前进行加密,以达到保护数据安全性的作用。 AES有5个主要步骤,分别为 n 密钥扩展 n 字节代换 n 行移位 n 列混合 n 轮密钥加 看一下AES的执行步骤 从图上还是挺直观可以看出整个步骤的。 其中5个主要步骤做的...

AES encryption is a symmetric cryptography algorithm. This means that the encryption and decryption process uses the same key for both processes. AES has been the standard for symmetric encryption for the last few decades, and is still widely used today for its secure encryption capabilities. AES...
