C# program to implement the cyclic redundancy check generator polynomial, by mod...

The class has a methode named make_CRC that gets a byte stream and start/end offsets then calculate and return a 16 bit CRC according to determined POLYNAMIAL.The POLYNAMIAL is a private field of the class.

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.

文件加密技术一例给文件加密的技术很多,其中又分为不同等级,以适合不同场合的需要.这里给出最简单的文件加密技术,即采用文件逐字节与密码异或方式对 文件进行加密,当解密时,只需再运行一遍加密程序即可.-file encryption technology to the case file encryption technologies lot, which will be divided into different levels, to suit the needs of different occasions. Here is the most simple file encryption technology, which adopts a case-by-byte file with the password or different ways to document encryption, decryption, only re-running again encryption procedures.
