使用PBE和三重DES加密文件-use of PBE and triple DES encryption document

aes算法java版，包含了源码和jar文件-Orangk"aes algorithm java version contains source and jar files

密码学文献有一个奇妙的发展历程，当然，密而不宣总是扮演主要角色。第一次世界大战前，重要的密码学进展很少出现在公开文献中，但该领域却和其它专业学科一样向前发展。-cryptography literature has a wonderful history, of course, close does not declare always played the leading role. Before the First World War, it was important to cryptography little progress emerged in the open literature. However, the area has other professional disciplines and the development of the same.

DES加密C代码带执行程序-DES encryption with C code enforcement procedures

实施一个小程序，以产生一对非对称密钥对要与RSA算法使用。

该源码描述了DES加密算法的硬件语言实现方式-The source described the hardware DES encryption algorithm realize the way language

加密文件软件源代码，把要加密文件拖动到生成软件上，按照软件提示要求即可进行保密措施．此源代码为本人校友编辑-document encryption software source code, document encryption to drive to generate software, in accordance with the software can suggest requirements for security measures. This source code for my alumni editor

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).

使用单片来进行CRC校验，可以位校验、半字节和字节校验-Using the single-chip to carry out CRC check, you can place check, half-byte and byte checksum

把AES算法封装成DLL方便掉用。 我只是做了简单修改，版权归原作者所有-put into AES Packaging swap used to facilitate DLL. I just made a simple change Lastings all the original author
