河豚的源代码

MD5加密，已经封装成一个C++类，只要调用该类就可方便使用-This C++ class serves as a wrapper for the Message Digest 5 code described in the Internet RFC 1321.

用ASP实现基于数据库的网页加密-ASP web-based database encryption

PE程序加密壳源程序 -PE procedure encryption shell source program

很 强 大 的 加 密 系 统。初 学 加 解 密者 好 处 大! -Very strong encryption system. Learning the benefits of encryption and decryption are great!

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

密码serpent算法源代码, 该算法是AES候选算法之一-Password serpent algorithm source code, the algorithm is AES, one of the candidate algorithm

一个ASP的SHA256加密算法-an ASP SHA256 encryption algorithm

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。。。。。。。。。。。。。。。。

古典加密算法,非常实用，有需要的可以下载，不需权限-this code is very good
