AES加密算法 2000年10月，NIST（美国国家标准和技术协会）宣布通过从15种侯选算法中选出的一项新的密匙加密标准。Rijndael被选中成为将来的AES。 Rijndael是在 1999 年下半年，由研究员 Joan Daemen 和 Vincent Rijmen 创建的。AES 正日益成为加密各种形式的电子数据的实际标准。 美国标准与技术研究院 (NIST) 于 2002 年 5 月 26 日制定了新的高级加密标准 (AES) 规范。-AES encryption algorithm in October 2000, NIST (National Institute of Standards and Technology Association) announced candidates from 15 kinds of algorithm selected a new encryption standard keys. Rijndael was selected to become the future of the AES. Rijndael is the second half of 1999, by researcher Joan Daemen and Vincent Rijmen created. AES encryption is increasingly becoming the various forms of de facto standard for electronic data. United States Institute of Standards and Technology (NIST) in May 26, 2002 developed a new Advanced Encryption Standard (AES) norms.

S-DES编程S-DES加密采用8和10明文作为密钥输入，有8个密文作为输出。使用同一密钥进行加密和解密。要求：CBC模式到解密版本增加。对话界面：在目录选项中选择加密或解密密钥输入明文或密文文档（对于二进制内容，。Txt文件，），建议加密或解密已完成2。输出：产生密文或明文文本3。提供：文档、源代码、可执行文件，通过加密实验得到运行结果。4分析雪崩效应文件：键下同一个显式改变文本在闭合处的差异，在同一个地方显式改变电位器在密文处的情况
