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! !)

说明：  编制程序，将输入的一行字符以加密的形式输出，然后将其解密，解密的字符串序列与输入的正文相比较，吻合时输出解密的正文，否则解密失败。 加密时，将每个字符的ascii码依次反复加上“4962873”中的数字，并在32（‘’）~122（‘z’）之间作模运算。解密与加密的顺序相反。例如输入正文“the result of 3 and 2 is not 8” 结果为： (Programming, the input line character output in an encrypted form, and then decrypted, the decrypted text sequence of characters compared with the input, output to decrypt the body of the agreement, otherwise the decryption failed. Encryption, ascii code of each character in turn repeatedly with &quot 4962873&quot in the figures, and 32 (' ' )~ 122 (' z' ) as a model between the operations. Decryption and encryption in reverse order. For example, enter the text &quot the result of 3 and 2 is not 8&quot results:)

自己动手写加壳程序，按照文档一步一步来，做你自己的加壳程序！(Packers to write himself, according to the document step by step, do your own packers!)

自己开发的一个des加密算法，可用作网络通信方面，希望对大家有帮助(Their development of a des encryption algorithm can be used as network communications, we want to help)

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. )

一种加密算法,可以直接对密文进行操作，而不需要知道相应的明文。(homomorphic encryption)

自主编写的一个简单的加密程序，算法思想简单(Written in a simple self-encryption algorithm is simple thoughts)

说明：  密码学BM算法的C++实现。可计算100阶m序列的生成多项式(Cryptography BM algorithm in C++. Computable 100 m sequence generator polynomial order)
