可以对文件进行加解密，这是自己编写的实验作业(Can encrypt and decrypt files, it is their job to prepare experimental)

量子密钥仿真 量子信息，BB84协议 量子密钥分配，安全通信，量子密码学，进十年内可能取代传统方法(the model of quantum key )

sha256计算代码，非常好用的代码，大家可以用这个代码直接计算哈希值，sha256实现 依次执行 SHA256Init、 SHA256Update SHA256Final 三个函数即可得到sha256结果(sha256 sourse code，Is very usefull)

加密文件夹,十分好用 使用visual basic环境编程(lock file)

3des算法code,已经通过visual c++编译．比一重des算法更加可靠！(3DES algorithm code, has passed visual c++ Compiler. Than one algorithm more reliable re-des!)

文件系统过滤驱动程序的框架，对于做文件透明加密的朋友很有帮助()

实现了ECC算法的加密解密，主要是对字符串的加解密。(Realize the ECC algorithm encrypt, decrypt, is mainly to the string encryption.)

整体思路 用createkey.java 文件来产生秘钥，用jiami.java 文件来实 现加密，用jiemi.java 文件来实现解密,用BigInteger.java 来实现 大数的表示及运算，用rsa.java 来实现前端图形界面显示。有关函 数见五个文件里的具体实现。 (The overall outlook createkey.java document used to generate secret keys, used to achieve jiami.java file encryption, used to achieve jiemi.java documents declassified by BigInteger.java to achieve expression of large numbers and calculations, using rsa.java to achieve front-end graphical interface display. Related functions, see the five concrete realization of the document.)

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,)

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)
