DES加密算法及有关说明(HTM)-DES encryption algorithm and the (HTM)

C++实现的椭圆曲线算法。已经写成一个库文件只要调用就行了-C++ Realized elliptic curve algorithm. Has been written in a library file as long as the call on the list

加密算法，java上的加密算法，对大家应该用帮助的一个加密算法。-encryption algorithm, java on the encryption algorithm, we should be used to help an encryption algorithm.

一个用移位思想实现的简单数据加密程序，因为不论是大写还是小写字母,其ASC码值都是按顺序排列的.故可以用相对应的ASC码值进行判断以及算法实现.-a shift ideology with a simple data encryption procedures, because both uppercase or lowercase letters, the value of ASC codes are arranged in chronological order according to the. It can be used to be the relative value of ASC code of judgment and algorithm.

对软件进行加密限制，以防止末经诃可的随意拷贝-right software encryption restrictions to prevent the end by sending copies to be arbitrary

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）。-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).

大数计算在公钥加密中起到了重要的作用，如何操作大数呢，该程序也许能帮你解决这个问题有所帮助。-calculated in the end, the public key encryption plays an important role in the operation of large numbers do, the program may be able to help you resolve this problem some help.

根据自己的加密要求可以修改，MD5加密处理单元。-According to their own requirements can be amended encryption, MD5 encryption processing unit.

这是我在学习Visual C++过程中做过的一个程序,可以作为大家学习Visual c++编程能力学习的参考,相信对读者会有所启发.-This is my learning Visual C conducted in the course of a procedure, As we can learn Visual Programming c learning ability of reference, I believe the readers will be inspired.
