IBE基于身份的加密系统的身份提取程序，使用VC6.0开发，即把身份转换成椭圆曲线上的点(IBE identity-based encryption system of the identity of extraction procedures, using VC6.0 development, namely, the identity into a point on the elliptic curve)

AES加解密C语言源代码，可直接运行通过，方便大家借鉴学习(AES encryption and decryption of C language source code, can be directly run by, we facilitate learning from)

Elgamal数字签名的一个大体验证,用于对一个文件的签名后在进行认证.一个VC开发的小程序.(Elgamal digital signature verification of a general for the signature of a document during the certification after. A small VC development process.)

PF140.514版digsilent软件的两个破解文件，按一定操作步骤即可免狗驱动，本人已在XP环境下使用，没有问题。希望对采用该软件的人有一点帮助！(Two crack file PF140.514 the version digsilent software, Free Dog certain steps to drive, I have XP environment, there is no problem. I hope the software a little help!)

自己写的一份RSA算法。可正常执行。控制台程序。(Write your own copy of the RSA algorithm. Can be performed normally. Console program.)

椭圆曲线的实现(ECC)，椭圆曲线算法是代数几何、数论等多个数学分支的一个交叉点，一直被人们认为是纯理论学科。而椭圆曲线密码体制，是基于椭圆曲线离散对数问题的一种公钥密码体制(Realization of elliptic curves (ECC), elliptic curve algorithm is algebraic geometry, a number of mathematical intersection of number theory and other branches, has been considered a purely theoretical discipline. The elliptic curve cryptosystem is based on elliptic curve discrete logarithm problem as a public-key cryptosystem)

说明：  一个关于加密音频，图像的VB程序，功能还算可以，希望可以帮到人！！(One on encryption of audio, images VB program, function OK, the desire to help people! !)

Themida的另类破解 附件提供的一个程序是用汇编写的PE信息小工具，用Themida1855加密，加密选择RISC-64 processor，全选加密可选项，并对部分API函数使用VM加密，入口虚拟系数选择15。
