AES BASE64编码

AES加密简介

高级加密标准Rijndael算法又被定为AES encryption standard by NIST.该 algorithm is designed to replace the Data Encryption Standard (DES) and operates within a symmetric block cipher framework. Its key length configurations include 128-bit, 192-bit, and 256-bit options, while maintaining a consistent block size of 128 bits. From 1998 onwards,NIST initiated the first round of AES candidate algorithm analysis, evaluation, and public solicitation, resulting in the selection of 15 candidate encryption algorithms for further scrutiny.

在1999年3月完成了第二轮AES-2的分析与测试工作之后，在随后的时间里继续跟进相关研究工作。美国政府于2000年10月2日正式宣
