通过C语言实现的AES CMAC加密和解密算法。上传文件为完整的VC6工程目录。AES加密算法即密码学中的高级加密标准（Advanced Encryption Standard，AES），又称Rijndael加密法，是美国联邦政府采用的一种区块加密标准。这个标准用来替代原先的DES，已经被多方分析且广为全世界所使用。经过五年的甄选流程，高级加密标准由美国国家标准与技术研究院 （NIST）于2001年11月26日发布于FIPS PUB 197，并在2002年5月26日成为有效的标准。AES 算法基于排列和置换运算。排列是对数据重新进行安排，置换是将一个数据单元替换为另一个。AES 使用几种不同的方法来执行排列和置换运算。 AES 是一个迭代的、对称密钥分组的密码，它可以使用128、192 和 256 位密钥，并且用 128 位（16字节）分组加密和解密数据。与公共密钥密码使用密钥对不同，对称密钥密码使用相同的密钥加密和解密数据。通过分组密码返回的加密数据的位数与输入数据相同。迭代加密使用一个循环结构，在该循环中重复置换和替换输入数据。(AES CMAC encryption and decryption algorithm C language. VC6 upload files to complete the project directory . AES encryption algorithm that is Cryptography Advanced Encryption Standard (Advanced Encryption Standard, AES), also known as Rijndael encryption method, a block encryption standard adopted by the U.S. federal government . This standard is used to replace the original DES, has been widely analyzed and multi used around the world . After five years of the selection process , the Advanced Encryption Standard by the American National Institute of Standards and Technology (NIST) on November 26, 2001 Posted in FIPS PUB 197, and May 26, 2002 became effective standards . AES algorithm based on permutation and substitution operations. Data re- arrangement is arranged , is replaced with a replacement unit of data to another . AES using several different methods to perform alignment and replacement operations. AES is an iterative , symmetric key block password , it can use 128, 192, and )

Hideseek可将秘密文件隐写到指定图片中，并可检测隐写信息，本文是对该软件的使用说明。(hide &seek to run the file through individual test run normally. Hidden secret documents can be written to the specified picture, and can detect steganographic message.)

编写的DES 对称加解密技术，可随时进行明文密文之间的转换，有需要的朋友可以下载测试！本人目的打算对后台数据库的敏感信息字段用该方法加密，然后用软件权限控制读取，这样即使直接SQL后台取数，也得不到明文数据。(Write DES symmetrical encryption technology, may at any time for conversion between plaintext cipher, friends in need can be download test! I purpose going to the backstage database of sensitive information field with the method of encryption, and then use software to read access control, so even if the SQL backend access directly, also can not get clear data. )
