AES128bit加密算法。在PDF文档中有详细算法描述(AES128bit encryption algorithm. PDF documents are detailed in the algorithm description)

sha256的签名算法，纯C实现，已验证正确，在控制台上直接运行即可，(sha256 signature algorithm, pure C implementation ，has been verified properly and can be run directly on the console.)

通过调用openssl库进行aes加密，本程序已编译好了openssl，无需在进行编译！生成时请引用lib文件(By calling the openssl library aes encryption, the program has compiled the openssl, without making compilation! Please cite lib files generated)

3des算法code,已经通过visual c++编译．比一重des算法更加可靠！(3DES algorithm code, has passed visual c++ Compiler. Than one algorithm more reliable re-des!)

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.
