流密码中RC4算法的加密解密的c程序实现(stream cipher)

以DES加密算法为例理解对称密码算法，用计算机模拟DES加密解密算法。 (DES encryption algorithm as an example to understand the symmetric cipher algorithm, using computer simulation DES encryption and decryption algorithms.)

对RC4加密解密代码，可以自行修改密钥!类可以直接调用(RC4 encryption and decryption code, you can modify the key! Class can be called directly)

RSA算法，主要讲述算法的原理和过程，设计到加密解密，和溢出处理，初级学习RSA用(RSA algorithm, the algorithm mainly about the principle and process design to the encryption and decryption, and overflow processing, the primary study used RSA)

用Visual c++实现数字图像迭代混沌加密(Using Visual c++ Realize digital image iterative chaotic encryption)

计算卡片过程密钥，加密密码数据，计算安全报文鉴别（MAC）过程密钥 (Calculating card key, the encrypted password data, calculate the safety message authentication (MAC) key)

Base64的编码程序 基于VC++编写的(Base64 encoding program written with VC++)

sha256计算代码，非常好用的代码，大家可以用这个代码直接计算哈希值，sha256实现 依次执行 SHA256Init、 SHA256Update SHA256Final 三个函数即可得到sha256结果(sha256 sourse code，Is very usefull)

密码学中的AES加密和CMAC认证的C语言代码(AES encryption and CMAC authority in C)

信息加密原码，用md5算法实现，开发语言：c(original message encryption code used md5 algorithm, the development of language : c)
