DES加密算法是应用很普遍的加密算法，本源代码是一个实现des加密揭密的演示程序。

OpenVPN is a robust and highly flexible tunneling application that uses all of the encryption, authentication, and certification features of the OpenSSL library to securely tunnel IP networks over a single TCP/UDP port.

base64加密算法源代码，比如现在的qq采样双层加密，其中外层加密就采用此算法-base64 encryption algorithm source code, such as the current two-tier encryption qq sampling, in which outer layer of encryption on the use of this algorithm

Inroduce the algorithm of RSA.

本软件设计一共分为两个模块：打包加密模块和发行模块。Ø  打包加密模块：实现视频文件的打包加密，音频文件的打包，CPL文件生成，PKL文件生成和创建一个本地资产映射文件MAP.asmap(管理有关影片及密钥相关信息用于发行)。Ø  发行模块：读取MAP.asmap中内容，根据encrypt一项判断视频是否加密。若加密根据MAP.asmap中相关内容和要发行的机器证书文件生成KDM文件和ASSETMAP，若未加密则只生成ASSETMAP文件。

该BM算法用来求二元域上长度为１１的序列的线性综合解-the BM algorithm used for binary domain length of the sequence of 11 linear integrated solution

128位的AES加密算法、可以在FPGA上实现。利用硬件描述语言Verilog实现。各个模块都有，行变换、列混淆、轮密钥加变换、密钥扩展，并且有说明文档PDPF格式的。有完整的测试程序Testbench。特别适合研究AES加密算法的爱好者。

对于这个问题的实现、刚刚给过一个程序，突然想起另外一种简单一些的方法，一并给出[笔者长期从事移动通信系统的无线链路调制与解调、物理层实现方面的工作。在移动通信GSM系统中，我们进行语音或者业务信道解调时，都会遇到CRC的求解。通常在硬件DSP实现时，特别是40位CRC求解时候，由于生成多项式有41项，DSP最大一次能处理40位，所以使用单个寄存器会遇到一些困难，那么以下这个程序将会解决这一困难（这是针对定点DSP、C55xx的编程实现方法）。]： -For the realization of this issue, just to have a program, suddenly reminded of another simpler way to be given [the author has long been engaged in mobile communication system modulation and demodulation of wireless links, the physical layer to achieve work. GSM in the mobile communications system, we have a voice or channel demodulation operations, it will encounter the solution of CRC. DSP hardware usually realize, especially when solving the 40 CRC, as the generation polynomial has 41, DSP can handle the largest 40, so using a single register may encounter some difficulties, then following this process will solve this One difficulty (which is for fixed-point DSP, C55xx realize programming methods). ]:
