大名鼎鼎的DES加密算法，内有html文档做出详细解释-famous DES encryption algorithm, which is html files provide a detailed explanation

DES 实现 包括 纯DES 3DES 和 CBC-DES achieve pure including 3DES and DES CBC

代码详细的将DES算法的加密过程描述详细，通过MFC进行界面化操作，整体界面良好，具有很强的可读性和很好的独立性，突出了C++的封装型和继承性的有点，值得参考。。。。。。。。。。。。。。。。

UPX1.9源代码(一个加壳工具)-UPX1.9 source code (a shell tools )

来自putty的大数运算代码，纯C实现，移植性好，RSA的最实现-Large numbers from the putty operation code, a pure C implementation, migration is good, RSA best to achieve

用VC实现MD5算法的源代码-with VC MD5 algorithm source code

While there are many AES cores around, this one is designed with LUT6 based FPGA architecture in mind from day one.  The AES Decryption Core for FPGA implements the decryption portion of the AES (a.k.a. Rijndael) algorithm described in the FIPS-197 specification. Key lengths of 128 / 192 / 256 bits are supported, each with a separate instantiation wrapper. Since the core is designed to take advantage of LUT6 based FPGA archit
