RSA

仿射密码体制加解密，较移位代换等加解密体制，更加优越。(Affine cipher encryption and decryption, a shift substitution and encryption and decryption system, more superior.)

sha256的签名算法，纯C实现，已验证正确，在控制台上直接运行即可，(sha256 signature algorithm, pure C implementation ，has been verified properly and can be run directly on the console.)

基于双缓冲过滤驱动的透明加密系统研究与实现(Based on double buffer transparent encryption system filter driver and Implementation Research)

说明：  使用维吉尼亚密码进行控制台编程，实现对英文文本文件的加解密！(Virginia password using the console program, to achieve the English version of the document encryption and decryption!)

基于miracl大数库的椭圆曲线EC的验证签名算法的c语言实现(Based on large numbers miracl library EC verification of an elliptic curve signature algorithm c-language implementation)

二进制文件操作工具 可以对二进制文件合并、分拆、加密、解密的工具，再对两个可执行文件进行合并后，显示第一个文件的信息，并且正常使用，第二个被忽略。(Binary file binary file manipulation tools can merge, split, encrypt, decrypt tool, and then the merger of two executable files, show the first file, and normal use, the second is ignored.)

OpenSSL的RSA算法应用举例。是用VC写的，有实用价值。(RSA algorithm of OpenSSL is used and given an example. Written with VC, there is practical value. )
