DES的实现，平时上课的实验，供大家参考。

基于 金邦达Gem USB KEY 的工商银行 PCSC 智能卡读取程序示例。自定义 APDU 命令交互，读取智能卡数据

My stuff is aimed at teaching, not efficiency. The others are probably much better implementations. The last one has both C++ and Java versions where my stuff is all C. So lots of choices!

关于A5算法的小程序-A5 algorithm on the small program

AES加密

MD5的全称是Message-digest Algorithm 5（信息-摘要算法），用于确保信息传输完整一致。本程序是c语言版的md5加密解密源码！-The full name of MD5 is Message-digest Algorithm 5 (Information- Summary of algorithm), to ensure the integrity of the information transmission line. This procedure is the c language version of the md5 encryption source code!

混合加密程序,RSA算法加密DES密钥,DES算法加密消息.很多通讯系统都是这样加密的-Hybrid encryption, RSA key DES encryption algorithm, DES encryption algorithm message. A lot of communication systems, are encrypted

是我设计的在DSB中隐藏语音的例子. 用ELANIX公司的SYSTEMVIEW打开运行. 其掩护信号和隐藏信号输入输出端均需设置语音源文件,比如自己录制的声音.-I designed the DSB concealed voice example. ELANIX company with the SYSTEMVI EW open operation. their cover and concealment signal input and output signals required to set up voice source, For example, recording their voices.

Mình đang gặp khó khăn phần tạo 关键 cho giải thuật mã hóa sử dụng DES。 胡志明芹源代码 C、 bạn nào có 旺角 cho mình tham khảo。 Làm ơn gửi vào địa chỉ 秀 giúp mình: vuquangbk0612@gmail.com

详细介绍了C函数。

哈希数据编码解码实现（Hash） 需安全openssl等安全证书-Hash data codec implementation (Hash) need to secure safety certificate openssl, etc.
