RSA

此为Keeloq算法的解密C代码，keeloq最常用于无线门锁装置。(KeeLoq is a proprietary hardware-dedicated NLFSR-based block cipher. The uni-directional command transfer protocol was designed by Frederick Bruwer, PhD, CEO at Nanoteq (Pty) Ltd)

atmel系列加密芯片资料，ATSHA204芯片手册。希望对编写驱动的朋友有所帮助！(Atmel series data encryption chip, manual ATSHA204 chip. Hope to write a driver for friends to help!)

用VC++开发的一款MFC程序，能很好地实现RSA加密和解密算法，对学习RSA加解密算法很有帮助(MFC with VC++ developed a program that can well realize RSA encryption and decryption algorithms, RSA encryption and decryption algorithms for learning helpful)

playfair 加密算法的实现，用一个例子做了展示(realize playfair algorithm，use a sample to show the algorithm)

这两个工程主要用CSP 1、CSPTEST 写的比较乱 主要是给当时一个朋友做参考调用的 完成非对称密钥的生成、导入、导出、加密、解密、对称的加密解密、签名、验证。 2、CSTTEST2 写的比前个好些，但是平时上班，下班自己也要写论文，所以花的时间也不太多，很多地方都偷懒了。比如文件大小我没有用NEW 而且指定了1024 有需要的朋友可以自己修改。这个工程主要是非对称的密钥的导出和导入，还有就是会话密钥的操作。(these two works mainly with a CSP. CSPTEST comparison was made mainly to the chaos when a friend called to refer to the completion of the non-symmetric key generation, importing and exporting, encryption, decryption, symmetric encryption and decryption, signature, the certification. 2, CSTTEST2 write better than in the previous months, but usually go to work and finish their own toilet paper so I spent the time is not too much, all of the lazy. For instance, file size I have not used the NEW 1024 and designated a need to amend their friends. The project mainly non-symmetric keys to the Export and Import, there is the session key operation.)

检测CRC编码 看CRC编码在传输后是否有错误 有变动 (Detection CRC codes to see whether the CRC coding errors in the transmission there is a change)

MD5VB2010实现MD5加密，计算机VB程序(MD5VB2010 achieve MD5 encryption, computer VB program)

加解密算法的实现，内部包含有多个加解密算法的实现，(Encryption and decryption algorithm, contains a number of internal encryption algorithm,)

RSA-MFC,基于MFC的RSA加密算法的实现，可以用于16进制文件的加解密(RSA-MFC, the MFC based on the realization of RSA encryption algorithm, can be used for 16-band file encryption and decryption)

pdf文件加密移除小软件。使pdf文件可打印可注释。(To remove pdf file encryption. So files can be printed comments)
