用C编程获取WPS的文件密码-C programming WPS access to the password file

快速MD5碰撞生成器，王小云改进版。这个生成器根据“构造前缀碰撞法”可以生成两个不同的文件，而这两文件的md5 sum却是一样的。 MD5 Collision Generator(win32 .exe) MD5 Collision Generator(source) -Fast MD5 collision generator, Xiaoyun Wang, improved version. The generator according to "construct the prefix collision" system can generate two different files, while the md5 sum of these two documents is the same.

C#程序来实现生成多项式的循环冗余校验,通过修改能校验多项式-C# program to implement the cyclic redundancy check generator polynomial, by modifying the polynomial can check

CRC校验中叠加和校验方法的生成，校验等功能函数源码。-CRC verification and validation methods of superposition generation, calibration source, such as performance function.

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。

通过对OpenSSL对称密码算法函数的调用，实现常用的对称加密。这个工具主要的功能已经实现，而且还可以对大文件进行加密，可能效率上还需进一步完善，因为对大文件加密时，太差劲的电脑会感觉有点卡！另外，它还可以对电影加密，不妨一试。-Symmetric cryptographic algorithm through OpenSSL function calls to achieve common symmetric encryption. The main function of this tool has been achieved, but also can encrypt large files, you may need to further improve efficiency, because the large file encryption, too bad the computer will be felt Dianka! In addition, it can encrypt the film, worth a try.
